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.

Respuesta :

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

Think of this logically. They want to spend less than $250 on the boat, so it can't be more than.

100+20*(7)=240
It would have to be A because B means they can spend over 250 dollars. C would be 260, which is over 250 and D means they could use the boat for more time, costing more money.
