A fruit stall sold oranges at 90¢ and guavas at 60¢ each. Jade bought some oranges and Linda bought some guavas from the stall. Jade spent $0.60 more than Linda, but had 3 fruits fewer than Linda.

1. How many oranges did Jade buy?
2. How much did Linda spend on the guavas?

	Oranges	Guavas
Number	1 u	1 u + 3
Value	0.9	0.6
Total value	0.9 u	0.6 u + 1.8

(a)
Number of oranges that Jade bought = 1 u
Number of guavas that Linda bought = 1 u + 3

Amount that Jade paid = 0.9 x 1 u = 0.9 u
Amount that Linda paid = 0.6(1 u + 3) = 0.6 u + 1.8

If Linda spent another $0.60, both Linda and Jade would spend the same amount.

0.9 u = 0.6 u + 1.8 + 0.6
0.9 u - 0.6 u = 1.8 + 0.6
0.3 u = 2.4

1 u = 2.4 ÷ 0.3 = 8

Number of oranges that Jade bought
= 1 u
= 8

(b)
Amount that Linda spent on the guavas
= 0.6 u + 1.8
= 0.6 x 8 + 1.8
= 4.8 + 1.8
= $6.60

Answer(s): (a) 8; (b) $6.60
