Jane and Beth are selling cupcakes and cakes to make money. They sell the cupcakes for $3 and cakes for $12. In order for Jane and Beth to make at least $300, what is the minimum number of cakes they must sell if they only sell 25 cupcakes?

So 25 cupcakes is 25x$3= $75 now she needs to sell 300-75= $225 worth of cakes... so 225/12= 18.75 or rounding up 19 cakes
