Question

at sals car repair shop, each of the 8 oil - change stations has a jug of windshield fluid. the graph shows how much fluid is left in each jug. amount of windshield washer fluid. if sal distributes all of the windshield washer fluid equally among the 8 jugs, how much will be in each jug? 1/2 gallon, 7/8 gallon, 1 1/7 gallons, 1 1/2 gallons

Explanation:

Step1: Count the amount of fluid at each mark

From the graph, there are 2 jugs with 0 gallons, 1 jug with $\frac{1}{2}$ gallon, 2 jugs with 1 gallon, and 3 jugs with $1\frac{1}{2}$ gallons.

Step2: Calculate the total amount of fluid

\[

$$\begin{align*} &(2\times0)+(1\times\frac{1}{2})+(2\times1)+(3\times1\frac{1}{2})\\ =&0 + \frac{1}{2}+2+(3\times\frac{3}{2})\\ =&\frac{1}{2}+2+\frac{9}{2}\\ =&\frac{1 + 4+9}{2}\\ =&\frac{14}{2}\\ =&7 \end{align*}$$

\]

Step3: Divide the total fluid by the number of jugs

There are 8 jugs. So the amount in each jug is $\frac{7}{8}$ gallon when distributed equally.

Answer:

$\frac{7}{8}$ gallon
