A movie theater sold a total of 520 adult and child tickets on a certain day. The theater sold 2.25 times as many adult tickets as child tickets. Each adult ticket cost $9 and each child ticket cost $3. How much revenue did the theater generate in ticket sales that day?
let Child ticket be x for adult 2.25x 2.25x* 9=520 solve for it ..... and 3x=520 solve for it .... and sum of that two adult ticket and children ticket will be the revenue generate in ticket sold for that day . hope u can solve it
