Question

Aiden´s mom calculated that in the previous month, their family had used 40% of their monthly income for gasoline, and 63% of that gasoline was consumed by the family´s SUV. If the family´s SUV used $261.45 worth of gasoline last month, how much money was left after gasoline expenses?

Answer 1

Explanation:

1. 261.45=.63x solve for x to find total gasoline expense

that value for x = .40Y, where Y is total monthly income solve for Y

then subtract x from Y

2. How many hours are in a day? multiply that by .10 to get 10% of a day. Is 2 hours and 30 minutes more or less than that?

Or 2.5 hours = x/24 hours where x would be the percent

solve for x then compare that percent to 10%
