can be used to determine how much money Manuel should save each week?
Answer:
$8.50 per wk
Step-by-step explanation:
$8.50x6=$51.00+$24.00=$75.00.
Answer:
Manuel must save at least $ 8.5 each week ( 6x ≥ 75 - 24)
Step-by-step explanation:
He has to save more than $75 - $24 = $51 for the next 6 weeks to have enough money for class trip
X: the amount must save each week
6x ≥ 51 ... divide 3 both sides
2x ≥ 17
x ≥ 17/2
x ≥ 8 1/2
