Stefan sells jin a bicycle for $140 and a helmet for $16. 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?

Step-by-step explanation:

so jin paid a total of (140 + 16) = 156

this is 130% of what stefan spent

so 130% of what stefan paid equals 156

let x represent what stefan paid

turn ur percent to a decimal

1.3x = 156

x = 156/1.3

x = 120 <== what stefan originally spent

and stefan made : (156 - 120) = $ 36 <==
