A fruit stall sold papayas at 60¢ and tomatoes at 30¢ each. Lynn bought some papayas and Sabrina bought some tomatoes from the stall. Lynn spent $0.90 more than Sabrina, but had 2 fruits fewer than Sabrina.

1. How many papayas did Lynn buy?
2. How much did Sabrina spend on the tomatoes?

	Papayas	Tomatoes
Number	1 u	1 u + 2
Value	0.6	0.3
Total value	0.6 u	0.3 u + 0.6

(a)
Number of papayas that Lynn bought = 1 u
Number of tomatoes that Sabrina bought = 1 u + 2

Amount that Lynn paid = 0.6 x 1 u = 0.6 u
Amount that Sabrina paid = 0.3(1 u + 2) = 0.3 u + 0.6

If Sabrina spent another $0.90, both Sabrina and Lynn would spend the same amount.

0.6 u = 0.3 u + 0.6 + 0.9
0.6 u - 0.3 u = 0.6 + 0.9
0.3 u = 1.5

1 u = 1.5 ÷ 0.3 = 5

Number of papayas that Lynn bought
= 1 u
= 5

(b)
Amount that Sabrina spent on the tomatoes
= 0.3 u + 0.6
= 0.3 x 5 + 0.6
= 1.5 + 0.6
= $2.10

Answer(s): (a) 5; (b) $2.10
