Question

Vince works for his uncle at a lumber yard. Vince’s pay is represented by this line graph.

The graph has time worked in hours on the horizontal line from 0 to 40 in increments of 10 and pay in dollars on the y-axis from 0 to 360 in increments of 20. A line start from (0, 0) and passes through (20, 180) and (40, 360).

How much is Vince paid for one hour of work?

A.
$3.60

B.
$9.00

C.
$9.50

D.
$12.00

Answer 1

To find out how much Vince is paid for one hour of work, we can determine his pay rate by looking at the information provided in the line graph.

From the graph:
- When Vince works 20 hours, he earns $180.
- When Vince works 40 hours, he earns $360.

We can calculate his pay for each hour by finding the pay rate.

First, let's determine the pay per hour after 20 hours:

\[
\text{Pay for 20 hours} = 180 \text{ dollars}
\]
\[
\text{Pay per hour} = \frac{180 \text{ dollars}}{20 \text{ hours}} = 9 \text{ dollars/hour}
\]

Now, let's check the pay for 40 hours:

\[
\text{Pay for 40 hours} = 360 \text{ dollars}
\]
\[
\text{Pay per hour} = \frac{360 \text{ dollars}}{40 \text{ hours}} = 9 \text{ dollars/hour}
\]

In both cases, Vince is paid $9.00 per hour.

Therefore, the correct answer is:

**B. $9.00**
