Question

Stefan sells Jin a bicycle for $138 and a helmet for $18. The total cost for Jin is 130% of what

Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How
much money did he make by selling the bicycle and helmet to Jin?
Stefan originally spent

Answer 1

1. $109.20 2. $46.80

Explanation:

Doing the math, we find that 30% of 156 (138+18) is 46.80, which answers the second part of this problem. Plugging this value into the first part of the equation gives us what Stefan originally paid.

Good luck! Hope this helps!
