the graph shows a proportional relationship between the number of computers produced at a factory per day. in three days, 36 computers are produced; 48 computers are produced in 4 days; and 60 computers are produced in 5 days. find the unit rate of computers per day using the graph. unit rate: computers per day
Answer
# Explanation:
## Step1: Recall unit - rate formula
The unit rate is the number of computers produced per 1 day. For a proportional relationship, the unit rate $r$ can be found using the formula $r=\frac{y}{x}$, where $y$ is the number of computers and $x$ is the number of days.
## Step2: Choose a data - point
We can use any of the given data - points. Let's use the fact that 36 computers are produced in 3 days. So, $y = 36$ and $x = 3$.
## Step3: Calculate the unit rate
$r=\frac{36}{3}=12$.
# Answer:
12
