To calculate the average weekly earnings, add the amounts Mark earned for the weeks and divide your total amount by 3 weeks.

$315 (Week 1)

+ $280 (Week 2)

+ $390 = (Week 3)

$985 (Total amount)

Now divide the total amount ($985) by 3 weeks to calculate the average Mark earned between the 3 weeks.

$985 ÷ 3 weeks = $328.33

Mark's average weekly earnings is $328.33.
