A fruit stall sold pomegranates at 80¢ and plums at 50¢ each. Marion bought some pomegranates and Fanny bought some plums from the stall. Marion spent $1.10 more than Fanny, but had 5 fruits fewer than Fanny.

1. How many pomegranates did Marion buy?
2. How much did Fanny spend on the plums?

	Pomegranates	Plums
Number	1 u	1 u + 5
Value	0.8	0.5
Total value	0.8 u	0.5 u + 2.5

(a)
Number of pomegranates that Marion bought = 1 u
Number of plums that Fanny bought = 1 u + 5

Amount that Marion paid = 0.8 x 1 u = 0.8 u
Amount that Fanny paid = 0.5(1 u + 5) = 0.5 u + 2.5

If Fanny spent another $1.10, both Fanny and Marion would spend the same amount.

0.8 u = 0.5 u + 2.5 + 1.1
0.8 u - 0.5 u = 2.5 + 1.1
0.3 u = 3.6

1 u = 3.6 ÷ 0.3 = 12

Number of pomegranates that Marion bought
= 1 u
= 12

(b)
Amount that Fanny spent on the plums
= 0.5 u + 2.5
= 0.5 x 12 + 2.5
= 6 + 2.5
= $8.50

Answer(s): (a) 12; (b) $8.50
