A fruit stall sold guavas at 80¢ and pomegranates at 60¢ each. Nora bought some guavas and Cathy bought some pomegranates from the stall. Nora spent $0.80 more than Cathy, but had 2 fruits fewer than Cathy.

1. How many guavas did Nora buy?
2. How much did Cathy spend on the pomegranates?

	Guavas	Pomegranates
Number	1 u	1 u + 2
Value	0.8	0.6
Total value	0.8 u	0.6 u + 1.2

(a)
Number of guavas that Nora bought = 1 u
Number of pomegranates that Cathy bought = 1 u + 2

Amount that Nora paid = 0.8 x 1 u = 0.8 u
Amount that Cathy paid = 0.6(1 u + 2) = 0.6 u + 1.2

If Cathy spent another $0.80, both Cathy and Nora would spend the same amount.

0.8 u = 0.6 u + 1.2 + 0.8
0.8 u - 0.6 u = 1.2 + 0.8
0.2 u = 2

1 u = 2 ÷ 0.2 = 10

Number of guavas that Nora bought
= 1 u
= 10

(b)
Amount that Cathy spent on the pomegranates
= 0.6 u + 1.2
= 0.6 x 10 + 1.2
= 6 + 1.2
= $7.20

Answer(s): (a) 10; (b) $7.20
