Answer:
Jack has to sell the old computers worth $8000
Explanation:
Jack is paid for selling used computers = $15 per hour plus 5% commission
Let the revenue generated from selling the computers by him = $x
He will be paid for 40 hours = $(40×15) = $600
Commission earned by selling x computers = $0.05x
Total amount earned by him in 40 hours week = 600 + 0.05x
If this amount is $1000,
$1000 = $(600 + 0.05x)
0.05x = 1000 - 600
0.05x = 400
x =
x = $8000
Therefore, Jack has to sell the old computers worth $8000.
