Question

Sosa received $90 in gift cards to Coffee Crazee and each drink she purchases costs $4.75. Sosa also received $75 in gift cards to Fran's Frappes and each drink she purchases cost $3.25. How many drinks will Sosa have to purchase in order to have the same amount remaining on the gift cards from both shops? * 33

Answer 1

90 -4.75x = 75 -3.25x

90-75= 4.75x-3.25x

x= 10

Explanation:

Answer 2

10 drinks

Explanation:

We can set up an equation to find the amount of drinks needed, x.

`90-4.75x = 75-3.25x`

Now let’s solve for x by isolating it on one side of the equation.

Subtract 75 from both sides:

`15 - 4.75x = -3.25x`

Add 3.25x to both sides:

`15-1.5x=0`

Add 1.5x to both sides:

`15 = 1.5x`

Divide both sides by 1.5:

`x = 10`

Hope this helped!
