Translate the problem situation to a system of equations. Do not solve.Bill & Jose's Discount Cinema sold adult tickets for $5.70 each and children's tickets for $1.60 each. Last Tuesday, a total of $489.90 was collected from 114 movie watchers. How many of each type were sold?
A. x + y = 489.90; 5.70x + 1.60y = $114 B. x + y = 7.30; 5.70x + 1.60y = $489.90 C. x + y = 114; 5.70x + 1.60y = $489.90 D. x - y = 114; 5.70x + 1.60y = $489.90
