Micah can have his oil changed in his car for $19.99, or he can buy the oil and filter and
change it himself for $8.79. How much would he save by changing the oil himself?

Answer 1

11.20

Explanation:

Multiply both equations by 100:

19.99=1999

8.79=879

1999-879=1120

Divide by 100:

1120/100=11.20 saved ................
