Question

Answer 1

Answer:

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 <==
