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

Answer:

Step-by-step 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%
