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

Question

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 determine how much Vince is paid for one hour of work, we can analyze the line on the graph.

From the graph, we can see:

• At 20 hours, Vince earns $180.
• At 40 hours, Vince earns $360.

To find the rate of pay per hour, we can calculate the pay per hour based on the information given.

1. Calculate the pay rate using the hours worked and the total pay.

   • At 20 hours: \[ \text{Pay per hour} = \frac{\text{Total Pay}}{\text{Total Hours}} = \frac{180}{20} = 9.00 \]

2. Confirm with the total at 40 hours:

   • At 40 hours: \[ \text{Pay per hour} = \frac{360}{40} = 9.00 \]

Both calculations show that Vince's pay for one hour of work is $9.00.

Thus, the correct answer is:

B. $9.00
