Translate the problem situation to a system of equations. Do not attempt to solve.Bill & Jose's Discount Cinema sold adults' tickets for $5.20 each and children's tickets for $2.30 each. Last Tuesday, a total of $526.00 was collected from 148 movie watchers. How many of each type of ticket were sold? (Let x represent the number of adults' tickets and y represent the number of children's tickets.)
A. x + y = 526.00, 5.20x + 2.30y = 148 B. x - y = 148, 5.20x + 2.30y = 526.00 C. x + y = 7.50, 5.20x + 2.30y = 526.00 D. x + y = 148, 5.20x + 2.30y = 526.00
