A fruit stall sold avocados at 70¢ and pomegranates at 40¢ each. Kathy bought some avocados and Jaslyn bought some pomegranates from the stall. Kathy spent $1.20 more than Jaslyn, but had 3 fruits fewer than Jaslyn.

1. How many avocados did Kathy buy?
2. How much did Jaslyn spend on the pomegranates?

	Avocados	Pomegranates
Number	1 u	1 u + 3
Value	0.7	0.4
Total value	0.7 u	0.4 u + 1.2

(a)
Number of avocados that Kathy bought = 1 u
Number of pomegranates that Jaslyn bought = 1 u + 3

Amount that Kathy paid = 0.7 x 1 u = 0.7 u
Amount that Jaslyn paid = 0.4(1 u + 3) = 0.4 u + 1.2

If Jaslyn spent another $1.20, both Jaslyn and Kathy would spend the same amount.

0.7 u = 0.4 u + 1.2 + 1.2
0.7 u - 0.4 u = 1.2 + 1.2
0.3 u = 2.4

1 u = 2.4 ÷ 0.3 = 8

Number of avocados that Kathy bought
= 1 u
= 8

(b)
Amount that Jaslyn spent on the pomegranates
= 0.4 u + 1.2
= 0.4 x 8 + 1.2
= 3.2 + 1.2
= $4.40

Answer(s): (a) 8; (b) $4.40
