Don has two jobs. For Job 1, he earns $7.55 an hour. For Job 2, he earns $8.45 an hour. Last week he worked at the first job for 10 hours and at the second job for 15 hours. What were his average earnings per hour? a $8.15 b $8.13 c $8.00 d $8.09

D. $8.09

Step-by-step explanation:

Get the total amount for Job 1 & Job 2 he worked for x amount of hours. The x amount of hours and the amount of earnings he get per hour is given to us:

Job 1: $7.55 x 10 = $75.50

Job 2: $8.45 x 15 = $126.75

Add two total costs from work:

$75.50 + $126.75 = $202.25

You add 10 + 15 to get 25 and we need this number for the average as he worked 25 hours in total:

$202.25 / 25 = $8.09 per hour

Don's average earnings per hour is $8.09 per hour.
