Bob buys cookies for $2 and a cake for $3 at a bake sale. If bob spends $15 to buy 6 items, how many of each does he buy
Answer provided by our tutors
let
x = the number of cookies Bob bought
y = the number of cakes Bob bought
Bob bough 6 items
x + y = 6
Bob spent $15
2x + 3y = 15
by solving the system of equations
x + y = 6
2x + 3y = 15
we find
x = 3 cookies
y = 3 cakes
