A fruit stall sold peaches at 60¢ and lemons at 30¢ each. Xuan bought some peaches and Gabby bought some lemons from the stall. Xuan spent $1.80 more than Gabby, but had 5 fruits fewer than Gabby.

1. How many peaches did Xuan buy?
2. How much did Gabby spend on the lemons?

	Peaches	Lemons
Number	1 u	1 u + 5
Value	0.6	0.3
Total value	0.6 u	0.3 u + 1.5

(a)
Number of peaches that Xuan bought = 1 u
Number of lemons that Gabby bought = 1 u + 5

Amount that Xuan paid = 0.6 x 1 u = 0.6 u
Amount that Gabby paid = 0.3(1 u + 5) = 0.3 u + 1.5

If Gabby spent another $1.80, both Gabby and Xuan would spend the same amount.

0.6 u = 0.3 u + 1.5 + 1.8
0.6 u - 0.3 u = 1.5 + 1.8
0.3 u = 3.3

1 u = 3.3 ÷ 0.3 = 11

Number of peaches that Xuan bought
= 1 u
= 11

(b)
Amount that Gabby spent on the lemons
= 0.3 u + 1.5
= 0.3 x 11 + 1.5
= 3.3 + 1.5
= $4.80

Answer(s): (a) 11; (b) $4.80
