Question

Cody worked 16 hours last week at the grocery store. His friend Sophie worked nine less than twice the number of hours that Cody did. If Cody made $156.80 and they both make the same hourly rate. how much did Sophie make?​

Answer 1

$225.40

Explanation:

Cody worked 16 hours.

Sophie:

2 × 16 - 9 = 32 - 9 = 23

Sophie worked 23 hours

Hourly rate for both calculated from Cody's information:

$156.80 / 16 hours = $9.80/hour

Sophie:

$9.80/hour × 23 hours = $225.40
