A music competition awarded 32 ribbons. The number of blue ribbons awarded was 3 less than the number of white ribbons. The number of red ribbons was five more than the number of blue ribbons. How many of each kind was awarded?
Answer provided by our tutors
b = w - 3
r = b + 5
b + r + w = 32
b + b + 5 + b + 3 = 32
3b = 24
b = 8
w = 11
r = 13
