Adult tickets for the school musical sold for 3.50 and student tickets sold for 2.50.
Three hundred twenty-one tickets were sold all together for 937.50.
How many of each kind of ticket were sold?
A + S = 321 —> S = 321 – A
3.50A + 2.50S = 937.50
3.50 (A) + 2.50 (321 – A) = 937.50
3.50A + (2.50)(321) – 2.50A = 937.50
3.50A – 2.50A = 937.50 – 802.50
A = 135
S = 321 – 135
S = 186
