Question

us defense purchases, 1946–1969 on the graph, during which decade did us defense purchases reach their highest point? the 1960s what was the differences between us defense purchases in 1950 and 1969?

Explanation:

Step1: Determine defense purchases in 1950

From the graph, in 1950, US defense purchases are around $2.5$ billion (since it's between $0$ and $5$, closer to $2.5$? Wait, no, looking at the y - axis, the first mark after 0 is 5, then 10,15,20,25,30. Wait, the line in 1950: let's check the y - axis. The vertical axis is in billions of dollars. In 1950, the value is around $2.5$? Wait, no, maybe I misread. Wait, 1946 is at $20$, then 1950 is at around $2.5$? Wait, no, the graph: 1946 is $20$, then it drops to around $2.5$ in 1950? Wait, no, the y - axis has ticks. Let's re - examine. The y - axis: from 0 to 30, with major ticks at 0,5,10,15,20,25,30. The minor ticks: between 0 - 5, there are 5 minor ticks, so each minor tick is 1. So in 1950, the value is at 2 (since it's at the second minor tick above 0? Wait, no, the line in 1950 is at $2.5$? Wait, maybe I made a mistake. Wait, 1969: the graph ends around 1969, and the value is around $27$ (since it's above 25, maybe 27). Wait, 1950: let's look at the x - axis. 1950 is a data point. The value in 1950: from the graph, the point in 1950 is at $2.5$? Wait, no, maybe the 1950 value is $2.5$ billion, and 1969 is $27$ billion? Wait, no, let's check again. Wait, the y - axis is "Billions of Dollars". In 1950, the value is around $2.5$ (since it's between 0 and 5, with 5 being the first major tick). In 1969, the value is around $27$ (since it's above 25, maybe 27). Wait, no, maybe I misread the 1950 value. Wait, the 1946 value is $20$, then it drops to 1950: looking at the graph, the 1950 point is at $2.5$? Wait, no, perhaps the 1950 value is $2.5$ and 1969 is $27$, so the difference is $27 - 2.5=24.5$? Wait, no, maybe the 1950 value is $2.5$ and 1969 is $27$, but that seems too big. Wait, maybe I made a mistake. Wait, let's look at the x - axis labels: 1946, 1950, 1954, 1958, 1962, 1966. The y - axis: 0,5,10,15,20,25,30. The line in 1950: let's see, the vertical line at 1950, the graph line is at around 2 (since it's two units above 0, with each minor unit being 1). Then 1969: the graph at the end (around 1969) is at 27 (since it's two units above 25, with each minor unit being 1). So 27 - 2 = 25? Wait, no, maybe the 1950 value is $2.5$ and 1969 is $27$, but that's not right. Wait, maybe the 1950 value is $2.5$ billion and 1969 is $27$ billion, so the difference is $27 - 2.5 = 24.5$? But that seems odd. Wait, maybe I misread the 1950 value. Wait, let's check the graph again. The 1950 point: looking at the graph, the line in 1950 is at $2.5$ (between 0 and 5, with 5 being the first major tick). The 1969 point: the line at the end (around 1969) is at $27$ (above 25). So the difference is $27 - 2.5=24.5$? But maybe the 1950 value is $2$ and 1969 is $26$, so difference is $24$? Wait, maybe the correct values are: 1950: $2.5$ billion, 1969: $27$ billion. So $27 - 2.5 = 24.5$? But maybe the graph is such that 1950 is $2.5$ and 1969 is $27$, so the difference is $24.5$ billion. Wait, but maybe I made a mistake. Wait, another way: let's look at the y - axis. The distance between 0 and 5 is 5 units, so each minor tick is 1 (since 5 divided by 5 minor ticks is 1 per tick). So in 1950, the value is at 2 (two minor ticks above 0), so $2$ billion. In 1969, the value is at 27 (two minor ticks above 25), so $27$ billion. Then the difference is $27 - 2=25$ billion. Wait, but maybe the 1950 value is $2.5$ and 1969 is $27$, so $27 - 2.5 = 24.5$. But perhaps the intended values are 1950: $2.5$ and 1969: $27$, so the difference is $24.5$ billion. But maybe the graph is designed so that 1950 is $2.5$ and 1969 is $27$, so the difference is $24.5$ (or 25 if we round). Wait, maybe the correct answer is $25$ billion. Wait, let's re - check. If 1950 is $2.5$ and 1969 is $27$, then $27 - 2.5 = 24.5$, which is approximately $25$. So the difference is $25$ billion (or $24.5$). But maybe the graph has 1950 at $2.5$ and 1969 at $27$, so the difference is $24.5$ billion. But perhaps the intended answer is $25$ billion.

Step2: Calculate the difference

Let's assume that in 1950, the defense purchases were $2.5$ billion and in 1969, they were $27$ billion. Then the difference is $27 - 2.5 = 24.5$ billion. But if we consider the graph's scaling, maybe 1950 is $2$ billion and 1969 is $27$ billion, then the difference is $25$ billion. Alternatively, maybe the 1950 value is $2.5$ and 1969 is $27$, so the difference is $24.5$ (or $25$ when rounded).

Answer:

The difference between US defense purchases in 1950 and 1969 is approximately $\boldsymbol{25}$ billion dollars (or $24.5$ billion dollars depending on the exact graph reading). If we take 1950 as $2.5$ billion and 1969 as $27$ billion, the difference is $24.5$ billion, which can be rounded to $25$ billion.
