asked • 05/09/22Juan is selling tickets for a high school play. Child tickets cost $3 and adult tickets cost $10.He sells 205 tickets and collects $1560.Setup a system of equations using C for number of child tickets and A for number of adult tickets and solve to find the number of each ticket sold.

Math, microeconomics or criminal justice
C+A =205
3C +10A = 1560
3C +3A = 3(205)= 615
subtract 3rd equation from 2nd
7A =1560-615 = 945
A = 945/7 = 135 adult tickets
C =205-135 =70 child tickets
3(70) +10(135) =210 +1350 = $1560
