Brad sold candy bars and cookies for a fundraiser at school. Candy bars sold for $3 and cookies sold for $5. He sold a total of 20 items and made $76. How many candy bars did Brad sell?
Answer provided by our tutors
3x+ 5y = 76
x + y = 20
or 3x + 3y = 60
subtracting , we get
2y = 16
y = 8
so x = 20-8 = 12
