PLEASE HELP ME
Travis sold cookies and cakes at a bakery.
The number of cookies he sold was 4 less than 3 times the number of cakes he sold.
He sold a total of 64 cookies and cakes.
Which system of equations can be used to determine the number of cookies, x, and cakes, y, Travis sold?
A.
x + y = 64
y = 4 – 3x
B.
x + y = 64
x = 3y – 4
C.
x + y = 64
y = 3x – 4
D.
x + y = 64
x = 4 – 3y
