The zoo charges $69.50 per adult ticket and $48.50 per childβs ticket. A group of 11
people paid $538.50 for tickets. Which system of equations could be used to find x, the number
of adult tickets purchased, and y, the number of children's tickets purchased?
a) 48. 5π₯ + 69. 5π¦ = 538. 5
π₯ + π¦ = 11
b) 48. 5π₯ + 69. 5π¦ = 11
π₯ + π¦ = 538. 5
c) 69. 5π₯ + 48. 5π¦ = 538. 5
π₯ + π¦ = 11
d) 69. 5π₯ + 48. 5π¦ = 11
π₯ + π¦ = 538. 5
c) 69.5π₯ + 48.5π¦ = 538.5
π₯ + π¦ = 11
