Answer 1

Stefan originally spent $110.

Stefan made a profit of $44.

Explanation:

Given that:

Stefan sold the bike and helmet for $137 and $17

Total amount = 137+17 = $154

This is 140% of the price Stefan originally paid.

Let,

x be the original price paid by Stefan

140% of x = $154

`(140)/(100)x=154\\1.4x = 154\\(1.4x)/(1.4)=(154)/(1.4)\\x=110`

Therefore,

Stefan originally paid $110 for the bicycle and helmet.

Profit made by Stefan = 154-110 = $44

Hence,

Stefan originally spent $110.

Stefan made a profit of $44.
