Question

Stefan sells Jin a bicycle for 135 and a helmet and a helmet for 19 the total cost for Jin is 140% of 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

Stefan spent $110 originally and lost $14 by selling the bicycle and helmet to Jin.

Step-by-step explanation:

To find out how much Stefan spent originally, we need to determine the 100% value. Since the total cost for Jin is 140% of Stefan's original expense, we can set up the equation: 140% = 135 + 19 + x, where x represents the amount Stefan spent originally. To solve for x, we need to convert 140% to decimal form, which is 1.4. So the equation becomes: 1.4x = 135 + 19. Simplifying, we get: 1.4x = 154. Dividing both sides by 1.4 gives us: x = 110. Therefore, Stefan spent 110 originally.

To calculate how much money Stefan made, we subtract the total cost for Jin from the amount Jin paid: $140 - ($135 + $19) = $140 - $154 = -$14. So Stefan lost $14 by selling the bicycle and helmet to Jin.

Answer 2

Originally Stefan spent $ 110, and made $ 30 selling the bike and helmet to Jin.

Step-by-step explanation:

Given that Stefan sells Jin a bicycle for $ 135 and a helmet for $ 19, and the total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet, to determine how much did Stefan spend originally and how much money did he make by selling the bicycle and helmet to Jin, the following calculation must be performed:

100 + 140 = 240

140 = 135 + 19

100 = X

(100 x (135 + 19)) / 140 = X

100 x 154/140 = X

15,400 / 140 = X

110 = X

So originally Stefan spent $ 110, and made $ 30 selling the bike and helmet to Jin.
