Question

Rachell buys a drink. She spends the same amount of money on her drink as Chuck spent on his candy, $1.20. Rachelle now has only 1/3 of the amount of money that she had before she brought the drink. How much money did Rachelle have before she bought the drink?

Answer 1

Rachell had $1.80 before she bought the drink

Explanation:

Rachell initially had $x.

She spent $1.20 on the drink, so now she has x - 1.20.

This is 1/3 of the original amount(x). So

`x - 1.20 = (x)/(3)`

`x = 3(x - 1.20)`

`x = 3x - 3.6`

`2x = 3.6`

`x = (3.6)/(2)`

`x = 1.8`

Rachell had $1.80 before she bought the drink
