Question

Stefan sells Jin a bicycle for $115 and a helmet for $17. The total cost for Jin is 110% 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?

Answer 1

Stephan spent $145.20

Answer 2

Stephan spent $145.20 I believe because 115+17=132 and to make it easier, 10% of 132 is 13.2(it’s like multiplying 132 by 0.1) and 100% of 132 is 132 so then you just take 132 and add 13.2 to get $145.20 and how much money he made would be $13.20
