A fruit stall sold pears at 60¢ and oranges at 30¢ each. Esther bought some pears and Gillian bought some oranges from the stall. Esther spent $2.40 more than Gillian, but had 4 fruits fewer than Gillian.

1. How many pears did Esther buy?
2. How much did Gillian spend on the oranges?

	Pears	Oranges
Number	1 u	1 u + 4
Value	0.6	0.3
Total value	0.6 u	0.3 u + 1.2

(a)
Number of pears that Esther bought = 1 u
Number of oranges that Gillian bought = 1 u + 4

Amount that Esther paid = 0.6 x 1 u = 0.6 u
Amount that Gillian paid = 0.3(1 u + 4) = 0.3 u + 1.2

If Gillian spent another $2.40, both Gillian and Esther would spend the same amount.

0.6 u = 0.3 u + 1.2 + 2.4
0.6 u - 0.3 u = 1.2 + 2.4
0.3 u = 3.6

1 u = 3.6 ÷ 0.3 = 12

Number of pears that Esther bought
= 1 u
= 12

(b)
Amount that Gillian spent on the oranges
= 0.3 u + 1.2
= 0.3 x 12 + 1.2
= 3.6 + 1.2
= $4.80

Answer(s): (a) 12; (b) $4.80
