The Polar Express charges $69.50 per adult ticket and $48.50 per child's 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) 48.5x + 69.5y = 538.5
x + y = 11
b) 48.5x + 69.5y= 11 = x + y = 538.5
c) 69.5x48. 5y = 538.5 x + y = 11
d) 69.5x + 48.5y= 11 = x + y = 538.5
