A fruit stall sold avocados at 60¢ and papayas at 30¢ each. Kimberly bought some avocados and Nora bought some papayas from the stall. Kimberly spent $1.20 more than Nora, but had 7 fruits fewer than Nora.

1. How many avocados did Kimberly buy?
2. How much did Nora spend on the papayas?

	Avocados	Papayas
Number	1 u	1 u + 7
Value	0.6	0.3
Total value	0.6 u	0.3 u + 2.1

(a)
Number of avocados that Kimberly bought = 1 u
Number of papayas that Nora bought = 1 u + 7

Amount that Kimberly paid = 0.6 x 1 u = 0.6 u
Amount that Nora paid = 0.3(1 u + 7) = 0.3 u + 2.1

If Nora spent another $1.20, both Nora and Kimberly would spend the same amount.

0.6 u = 0.3 u + 2.1 + 1.2
0.6 u - 0.3 u = 2.1 + 1.2
0.3 u = 3.3

1 u = 3.3 ÷ 0.3 = 11

Number of avocados that Kimberly bought
= 1 u
= 11

(b)
Amount that Nora spent on the papayas
= 0.3 u + 2.1
= 0.3 x 11 + 2.1
= 3.3 + 2.1
= $5.40

Answer(s): (a) 11; (b) $5.40
