Question

Stefan sells Jin a bicycle for $173 and a helmet for $19. The total cost for Jin is 160% 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

Answer: $72

Explanation:

To find out how much Stefan spent originally, we need to divide the total cost for Jin by 160% (or 1.6). Let's call the og cost "x."

160% of x is equal to the total cost for Jin, which is $173 for the bike and $19 for the helmet.

So, we can set up the equation:

1.6x = 173 + 19

Simplifying this equation, we have:

1.6x = 192

To find the value of x, we divide both sides of the equation by 1.6:

x = 192 / 1.6

Calculating this, we find that Stefan spent $120 originally.

To determine how much money Stefan made by selling the bike and helmet to Jin, we subtract the original cost from the total cost Jin paid:

$173 + $19 - $120 = $72

Stefan made $72 by selling the bicycle and helmet to Jin.
