Ryan worked for 7 hours and earned $52.50. If this rate increased by 4%, what will he earn if he works for 8 hours?

$62.40

Step-by-step explanation:

7 hours of work: $52.50

1 hour of work:

$52.50 / 7 = $7.5

$7.5 per hour

If Ryan's rate increased by 4%, what would he earn per hour?

$7.5 * 1.04 = $7.8

New hourly wage: $7.8 per hour

For 8 hours of work:

$7.8 * 8 = $62.4 = $62.40

$62.40

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
