Question

The Mitchells are renting a boat for the day. It costs $100, plus $20 for each hour. They have to pay for a whole hour even if they are not out there for a whole hour. For example if they boat for 3 and a half hours, they have to pay for 4 hours.

They don't want to spend more than $250 for the day. How many hours can they boat? Write an inequality and solve.


A)
100 + 20x ≤ 250. They can boat for 7 hours.


B)
100 + 20x ≥ 250. They can boat for 8 hours.


C)
100 + 20x ≤ 250. They can boat for 8 hours.


D)
100 + 20x ≥ 250. They can boat for 7 hours.

Answer 5

\[250-100+20x=10\]\[250-100=150\]\[150-20x=10\]\[150-10=140\]\[140\div20=x\]

Answer 6

What is 140/20?

Answer 7

140?20 = 7?

Answer 8

Please don't give out direct answers. We're here to help, not do their work for them.

Answer 9

100 + 20x <= 250
20x <= 250 - 100
20x < = 150
x < = 150/20
x <= 7.5...so they have to pay for 8 hrs

are you sure it is not C

Answer 10

Yep, 7 hours :)

Answer 11

They have a budget of 250 and 8 hours would be 260.
