Question

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. 5𝑥 + 69. 5𝑦 = 538. 5
𝑥 + 𝑦 = 11
b) 48. 5𝑥 + 69. 5𝑦 = 11
𝑥 + 𝑦 = 538. 5
c) 69. 5𝑥 + 48. 5𝑦 = 538. 5
𝑥 + 𝑦 = 11
d) 69. 5𝑥 + 48. 5𝑦 = 11
𝑥 + 𝑦 = 538. 5

Answer 1

c) 69.5𝑥 + 48.5𝑦 = 538.5
𝑥 + 𝑦 = 11
