Organizers at the concert announced that 350 tickets had been sold and thay $19250 had been raised through ticket sales alone. which of the following systems could be used to find the number of tickets for bench seats, B, and the number of tickets for lawn seats, L, that were sold for the concert?
Accepted Solution
A:
Answer:Tickets to sit on the bench (b) = 150Tickets to sit on the lawn (l) = 200Step-by-step explanation:Tickets to sit on a bench (b)cost $75 each.Tickets to sit on the lawn (l) cost $40 each350 tickets had been sold$19,250 had been raised through tickets salesThis forms a simultaneous equation:b + l = 350 ... (i)75b + 40l = 19,250 ... (ii)Multiplying (i) by 40 and (ii) by 1 we get;40b + 40l = 14,000 ... (i)75b + 40l = 19,250 ... (ii)Subtracting (ii) - (i) we get;35b = 5250b = 5250 ÷ 35 = 150So there were 150 tickets to sit on a bench and 350 - 150 = 200 tickets to sit on the lawn.
