6 9
Answer:
9 hours
Step-by-step explanation:
Abe's charge = Gabe's charge
$130+($70/hr)h = $40+($80/hr)h
Then 130 + 70h = 40 + 80h, or
90 = 10h, or h = 90/10 = 9
When 9 hours have passed, the amount charged by each person will be temporarily equal.
The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
.23 and .24 is your answer.
