A fruit stall sold dragon fruits at 80¢ and pomegranates at 50¢ each. Irene bought some dragon fruits and Cindy bought some pomegranates from the stall. Cindy spent $2.60 less than Irene, but had 2 fruits more than Irene.

1. How many pomegranates did Cindy buy?
2. How much did Irene spend on the dragon fruits?

	Dragon Fruits	Pomegranates
Number	1 u	1 u + 2
Value	0.8	0.5
Total value	0.8 u	0.5 u + 1

(a)
Number of dragon fruits that Irene bought = 1 u
Number of pomegranates that Cindy bought = 1 u + 2

Amount that Irene paid = 0.8 x 1 u = 0.8 u
Amount that Cindy paid = 0.5(1 u + 2) = 0.5 u + 1

If Cindy spent another $2.60, both Cindy and Irene would spend the same amount.

0.8 u = 0.5 u + 1 + 2.6
0.8 u - 0.5 u = 1 + 2.6
0.3 u = 3.6

1 u = 3.6 ÷ 0.3 = 12

Number of pomegranates that Cindy bought
= 1 u + 2
= 12 + 2
= 14

(b)
Amount that Irene spent on the dragon fruits
= 0.8 u 
= 0.8 x 12 
= $9.60

Answer(s): (a) 12; (b) $9.60
