Answer:
D
Explanation:
Hello There!
So the sum of the cakes (y) and cookies (x) is 64
so x + y = 64
It says that the amount of cookies he sold was 4 less then 3 times the number of cakes he sold
x = cookies
y = cakes
he sold 3 times the amount of cakes (y) - 4
so x=3y-4
So we can conclude that the answer would be D
