Answer:
2 hours
Step-by-step explanation:
According to the information provided you can say that for company A, the total cost is equal to 90 for the number of hours plus the 50 fee. For company B, the total cost is equal to 70 for the number of hours plus 90.
90x+50= 70x+90
x= number of rental hours
Then, you have solve for x:
90x-70x=90-50
20x=40
x=40/20
x= 2
The cost for both companies is the same for 2 rental hours.
Answer:
h = 2 hrs
Step-by-step explanation:
Mr Clark needed to rent a moving Van.
Company A charges
cost = 50 + 90(h)
where
h = number of hours used
Company B charges
cost = 90 + 70(h)
where
h = number of hour used
The number of rental hours when both companies cost is same is when both the cost equation is equal to each other.
Therefore,
50 + 90(h) = 90 + 70(h)
50 - 90 = 70h - 90h
-40 = -20h
divide both sides by -20
h = -40/-20
h = 2 hrs
