A fruit stall sold peaches at 60¢ and limes at 30¢ each. Roshel bought some peaches and Jean bought some limes from the stall. Roshel spent $1.20 more than Jean, but had 6 fruits fewer than Jean.

1. How many peaches did Roshel buy?
2. How much did Jean spend on the limes?

	Peaches	Limes
Number	1 u	1 u + 6
Value	0.6	0.3
Total value	0.6 u	0.3 u + 1.8

(a)
Number of peaches that Roshel bought = 1 u
Number of limes that Jean bought = 1 u + 6

Amount that Roshel paid = 0.6 x 1 u = 0.6 u
Amount that Jean paid = 0.3(1 u + 6) = 0.3 u + 1.8

If Jean spent another $1.20, both Jean and Roshel would spend the same amount.

0.6 u = 0.3 u + 1.8 + 1.2
0.6 u - 0.3 u = 1.8 + 1.2
0.3 u = 3

1 u = 3 ÷ 0.3 = 10

Number of peaches that Roshel bought
= 1 u
= 10

(b)
Amount that Jean spent on the limes
= 0.3 u + 1.8
= 0.3 x 10 + 1.8
= 3 + 1.8
= $4.80

Answer(s): (a) 10; (b) $4.80
