3 cupcakes:
When 5 drops, the remaining are;
73-5=68 cupcakes
13 containers will hold 65 cupcakes
It's the last choice. In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20. I'm more used to writing them down instead of across, but there you have it anyways
I guess it might be 3/2 which would be 1 1/2
