a racket cost $12.00 more than a bat. the cost of two rackets and three bats is $619.
using x ato represent the cost, in dollars, of a bat.
(i) write an algebraic expression for the cost of a racket
racket cost = x+12
(ii) write an algebraic equation to represent the total cost of the two rackets and three bats
2(x+12) + 3x = 619
(iii) solve the equation and hence, determine the cost of a racket
5x +24 = 619
5x = 595
x = $119 (cost of a bat)
x+12= $131 (cost of a racket)
