Answer provided by our tutors
let
x = the number of bags of candy
y = the number of bags of cookies
Bags of candy cost $7.00, and bags of cookies cost $2.50, and sales equaled $31.50 in total:
7x + 2.50y = 31.50
There were 5 more bags of cookies than candy sold:
y = x + 5
by solving the system of equations:
7x + 2.50y = 31.50
y = x + 5
we find:
x = 2 bags of candy
y = 7 bags of cookies
