Answer:
$309
Step-by-step explanation:
The computation of the gross earning for the week is as follows:
Given that
Payment of $7.15 × 8 = $57.2 or payment of each unit produced whichever is greater
On monday
= 90 units × $0.60
= $54
But the greater is $57.2
On tuesday
= 114 units × $0.60
= $68.4
On Wednesday
= 82 units × $0.60
= $49.20
But the greater is $57.2
On thursday
= 112 units × $0.60
= $67.20
On friday
= 98 units × $0.60
= $58.80
Now the earnings for the last week is
= $57.20 + $68.4 + $57.20 + $67.20 + $58.80
= $308.80
= $309
