Gina’s father said that she would get $130 and a new bicycle if she mows the lawn 30 times. After mowing the lawn 20 times, she got a new bike and $50. If this represents the total amount Gina has earned up to that time, how much did the bike cost?

or:Gina\u2019s father said that she would get $130 and a new bicycle if she mows the lawn 30 times. After mowing the lawn 20 times, she got a new bike and $50. If this represents the total amount Gina has earned up to that time, how much did the bike cost?

or:Well first, you have to simplify the ratio. 30/130=4.33. So now 30 times 4.33 is 130. Now you multiply 20 by 4.33 and get 86.6. This is how much Gina got after mowing the lawn 20 times. You now subtract 86.6-50=36.6. The bike was $36.60.
