Question

The Dakotas rented a minivan for their family vacation. When they returned

from vacation, the total bill for the van was $575. The standard weekly rate
from the rental company is $355 plus $55 for each additional day of usage.
How many additional days did the Dakotas have the minivan?

Answer 1

4 additional days.

Explanation:

So the total charge is $575.

It costs $355 for 1 week of use of the van.

1 week is 7 days.

It costs $55 for each extra day of use of the van.

575=55d+355

d is for the unknown extra amount of days.

subtract 355 from both sides

220=55d

divide by 55 on both sides

4=d

So, the Dakotas used the van for 4 additional days. So in total the used the van for 4+7 days.

4+7=11 total days.

But the answer to the question is 4 days, because it specifically ask for additional days.
