A grocery store employee earns $15 an hour. He earns $20 an hour for each hour over 40 that he works in the week. Use the graph to solve for how much he will make for the week if he works 55 hours.

(1 point)

$900

$825

$1,500

$1,100

Answer 1

First 40 hours at $15/hr: 40 × $15 = $600 (matches the point (40, 600)).
Overtime 15 hours at $20/hr: 15 × $20 = $300.
Total pay = $600 + $300 = $900.

Answer: $900
