Question

How much will Dustin have raised based on these two donations?

Answer 1

The first step to find the answer is to convert the miles he run to feet, using the conversion factor given in the statement:

`5miles\cdot(5280ft)/(1mile)=26400ft`

Now, divide this number by 40 (this is because his neighbor is going to pay for every 40 feet):

`(26400ft)/(40ft)=660`

Now, multiply this number by $0.25 and then add it to the product of 5 and $18 (which is the amount paid by his aunt for every mile run):

`0.25\cdot660+18\cdot5=255`
