So they need $125 to start a slime business.
To get money Carrie start to sell cupcakes for 0.50 cents

Juanita will be selling cards for $2.25

Juanita is selling cards for $2.25 and she is selling at least 35 of them

Carrie is selling cupcakes for 0.50 cents and the number of cupvakes is three times the number of cards so we will multiply 35 x 3=105 number of cupcakes

Then we will multiply 0.50 cents x 105= $53.2 on the cupcakes.

After that, we will multiply $2.25 x 35 for the cards = 78.5

Finally add them together
78.5
+53.3
---------
$ 131.8

So they will have $131.8 after selling cupcakes and cards.
