Answer:
Rachell had $1.80 before she bought the drink
Step-by-step 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
[tex]x - 1.20 = \frac{x}{3}[/tex]
[tex]x = 3(x - 1.20)[/tex]
[tex]x = 3x - 3.6[/tex]
[tex]2x = 3.6[/tex]
[tex]x = \frac{3.6}{2}[/tex]
[tex]x = 1.8[/tex]
Rachell had $1.80 before she bought the drink
