15 + 2(2 * 4) - 4^2
= 15 + 2(8) - 4^2
= 15 + 16 - 4^2

Its D since 6 would go to both numbers in the parentheses.
If 1/5 of the cakes are fruitcakes, then
![1- \frac{1}{5} = \frac{4}{5}](https://tex.z-dn.net/?f=1-%20%5Cfrac%7B1%7D%7B5%7D%20%3D%20%5Cfrac%7B4%7D%7B5%7D%20)
of the cakes are sponge cakes. To convert to a percentage, we simply multiply by 100, for a result of
![\frac{4}{5}*100= \frac{400}{5}=80](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%2A100%3D%20%5Cfrac%7B400%7D%7B5%7D%3D80%20%20)
