Question

The cost of 2 rackets and 3 squash balls is £21.63 the cost of 5 rackets and 7 squash balls is £52.90 work out the cost of one racket and one squash ball

Answer 1

Let r = cost per racket

s = cost per squash ball

2r + 3s = £21.63---->14r + 21s = £151.41

5r + 7s = £52.90--->15r + 21s = £158.70

---------------------------

r = £7.29, s = £2.35
