Dale rented a truck for one day. There was a base fee of $16.95 , and there was an additional charge of 77 cents for each mile driven. Dale had to pay $149.

Question

i dont know how to do this

Answer 1

Hi Makinzie - we need to set up an equation to solve this. 

 

1) We need to use the same units, so let's convert everything to dollars... 77 cents becomes 0.77 dollars

 

2) Let's call the number of miles that Dale drove "x"

 

3) The total amount he spent was $149 (which is the base fee of $16.95 + miles he drove multiplied by 0.77 per mile)

 

4) So our equation is 149 = 16.95 + 0.77x

 

5) Subtract 16.95 for each side to get 132.05 = 0.77x

 

6) Divide both sides by 0.77 to get x = 171.4935 miles

 

Dale drove approximately 171.5 miles
