Which equation represents the number of price increases, x, such that the amount money made is $1800?
The theater club at a high school sells 240 tickets to a show at $5 per ticket. The club then considers raising the price of a ticket. The club manager estimates that for every $2.50 increase in price, the number of tickets sold decreases by 30. The theatre raises the price of a ticket and makes $1800.
A. 1800 = (5x + 2.5) (210x)
B. 1800 = (5 + 2.5x) (210x)
C. 1800 = (5x + 2.5) (240 - 30x)
D. 1800 = (5 + 2.5x) (240 - 30x)
