A fruit stall sold guavas at 70¢ and dragon fruits at 40¢ each. Marion bought some guavas and Hilda bought some dragon fruits from the stall. Hilda spent $0.40 less than Marion, but had 8 fruits more than Marion.

1. How many dragon fruits did Hilda buy?
2. How much did Marion spend on the guavas?

	Guavas	Dragon Fruits
Number	1 u	1 u + 8
Value	0.7	0.4
Total value	0.7 u	0.4 u + 3.2

(a)
Number of guavas that Marion bought = 1 u
Number of dragon fruits that Hilda bought = 1 u + 8

Amount that Marion paid = 0.7 x 1 u = 0.7 u
Amount that Hilda paid = 0.4(1 u + 8) = 0.4 u + 3.2

If Hilda spent another $0.40, both Hilda and Marion would spend the same amount.

0.7 u = 0.4 u + 3.2 + 0.4
0.7 u - 0.4 u = 3.2 + 0.4
0.3 u = 3.6

1 u = 3.6 ÷ 0.3 = 12

Number of dragon fruits that Hilda bought
= 1 u + 8
= 12 + 8
= 20

(b)
Amount that Marion spent on the guavas
= 0.7 u 
= 0.7 x 12 
= $8.40

Answer(s): (a) 12; (b) $8.40
