Answer 1

Stefan spent $120 originally to buy the bike and helmet and made $36 by selling them to Jin.

Step-by-step explanation:

To find out how much Stefan spent originally, we need to divide the total cost for Jin by 130%.

Let's call the original amount x.

Jin's total cost is 130% of x, which can be expressed as 1.3x.

We know that the total cost for Jin is $140 for the bike + $16 for the helmet = $156.

So we have the equation 1.3x = $156. To solve for x, divide both sides of the equation by 1.3. x = $156 / 1.3 = $120.

Therefore, Stefan spent $120 originally to buy the bike and helmet.

To find out how much money Stefan made by selling the bike and helmet, we subtract the original amount spent from the total cost for Jin.

Money made = $156 - $120 = $36.

Answer 2

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 <==
