Rachel spend $1.20 on her drink. She has now 1/3 of the amount of money that she had before she bought the drink. How much money did she have before she bought a drink?

To find out how much money Rachel had before she bought the drink, we can use the information given in the question. Let's break down the problem step by step:

1. We know that Rachel spent $1.20 on her drink.
2. After buying the drink, she has 1/3 of the amount of money left that she had before making the purchase.
3. Let's assume that the amount of money she had before buying the drink is "x".

To solve the problem, we need to set up an equation using the information given. The equation would be:

x - $1.20 = (1/3) * x

Now, let's solve the equation step by step:

1. Distribute the (1/3) to both terms on the right side:

x - $1.20 = (x/3)

2. Get rid of the fraction by multiplying through by 3:

3 * (x - $1.20) = x

3x - $3.60 = x

3x - x = $3.60

2x = $3.60

3. Divide both sides of the equation by 2 to isolate "x":

x = $3.60 / 2

x = $1.80

Therefore, Rachel had $1.80 before she bought the drink.

2/3x = 1.2

x = 1.2 / (2/3)

x = 1.2 * (3/2)

x = 1.80
