Question
When the teacher buys tennis rackets for his gym class, he must buy five more than three times as many tennis balls. Rackets cost $20 each and ball cost $1.50 each. How much does the teacher spend if he needs 17 tennis rackets?

rackets=5+3*B or B=(R-5)/3
cost=20R+1.5B
=20*17+1.5(17-5)/3
cost=20R+1.5B
=20*17+1.5(17-5)/3

(17 * 3) + 5 = 56 balls
(17 * 20) + (56 * 1.5) = ?
(17 * 20) + (56 * 1.5) = ?
