Kieva made 8 cupcakes. 8 * 5 + 8 = 48 desserts.
In order to get this, you just have to try out different numbers of cupcakes and adjust based on whether it's too many desserts total, or not enough.
Another way to figure it out is to say that 1 cupcake + 5 cookies = 6 desserts. Then just divide 48 by 6 to get 8 which will then show you that Kieva made 8 cupcakes.
