A fruit stall sold dragon fruits at 90¢ and papayas at 60¢ each. Cindy bought some dragon fruits and Elyse bought some papayas from the stall. Cindy spent $0.60 more than Elyse, but had 5 fruits fewer than Elyse.

1. How many dragon fruits did Cindy buy?
2. How much did Elyse spend on the papayas?

	Dragon Fruits	Papayas
Number	1 u	1 u + 5
Value	0.9	0.6
Total value	0.9 u	0.6 u + 3

(a)
Number of dragon fruits that Cindy bought = 1 u
Number of papayas that Elyse bought = 1 u + 5

Amount that Cindy paid = 0.9 x 1 u = 0.9 u
Amount that Elyse paid = 0.6(1 u + 5) = 0.6 u + 3

If Elyse spent another $0.60, both Elyse and Cindy would spend the same amount.

0.9 u = 0.6 u + 3 + 0.6
0.9 u - 0.6 u = 3 + 0.6
0.3 u = 3.6

1 u = 3.6 ÷ 0.3 = 12

Number of dragon fruits that Cindy bought
= 1 u
= 12

(b)
Amount that Elyse spent on the papayas
= 0.6 u + 3
= 0.6 x 12 + 3
= 7.2 + 3
= $10.20

Answer(s): (a) 12; (b) $10.20
