Jim's car repair charges $50 plus $16 for every pint of oil. Sam's car repair charges $80 plus $14 for every pint of oil. At how many pints of oil would the cost be the same?

5 pints of oil for 8 dollars

Step-by-step explanation:

1.65 dollars for 1 pint

3.4/2=1.7 dollars for 1 pint

8/5=1.6 dollars for 1 pint

17.6/10=1.76 dollars for 1 pint

33/20=1.65 dollars for 1 pint

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

6 on both sides and twelve on the top and the bottom
