A fruit stall sold dragon fruits at 60¢ and avocados at 30¢ each. Elyse bought some dragon fruits and Jaslyn bought some avocados from the stall. Elyse spent $0.90 more than Jaslyn, but had 8 fruits fewer than Jaslyn.

1. How many dragon fruits did Elyse buy?
2. How much did Jaslyn spend on the avocados?

	Dragon Fruits	Avocados
Number	1 u	1 u + 8
Value	0.6	0.3
Total value	0.6 u	0.3 u + 2.4

(a)
Number of dragon fruits that Elyse bought = 1 u
Number of avocados that Jaslyn bought = 1 u + 8

Amount that Elyse paid = 0.6 x 1 u = 0.6 u
Amount that Jaslyn paid = 0.3(1 u + 8) = 0.3 u + 2.4

If Jaslyn spent another $0.90, both Jaslyn and Elyse would spend the same amount.

0.6 u = 0.3 u + 2.4 + 0.9
0.6 u - 0.3 u = 2.4 + 0.9
0.3 u = 3.3

1 u = 3.3 ÷ 0.3 = 11

Number of dragon fruits that Elyse bought
= 1 u
= 11

(b)
Amount that Jaslyn spent on the avocados
= 0.3 u + 2.4
= 0.3 x 11 + 2.4
= 3.3 + 2.4
= $5.70

Answer(s): (a) 11; (b) $5.70
