25

Step-by-step explanation:

Let x be the no. of cupcakes and y be the number of cakes

We are given that they only sell 25 cupcakes

So, equation becomes : ---A

Cost of 1 cupcake = $3

Cost of x cupcakes = 3x

Cost of 1 cake = $12

Cost of y cakes = 12y

We are given that  Jane and Beth to make at least $300

So, ---B

Substitute the value of x from A in B

Hence  the minimum number of cakes they must sell if they only sell 25 cupcakes is 25
