A fruit stall sold peaches at 70¢ and pomegranates at 40¢ each. Raeann bought some peaches and Emily bought some pomegranates from the stall. Emily spent $1.30 less than Raeann, but had 2 fruits more than Raeann.

1. How many pomegranates did Emily buy?
2. How much did Raeann spend on the peaches?

	Peaches	Pomegranates
Number	1 u	1 u + 2
Value	0.7	0.4
Total value	0.7 u	0.4 u + 0.8

(a)
Number of peaches that Raeann bought = 1 u
Number of pomegranates that Emily bought = 1 u + 2

Amount that Raeann paid = 0.7 x 1 u = 0.7 u
Amount that Emily paid = 0.4(1 u + 2) = 0.4 u + 0.8

If Emily spent another $1.30, both Emily and Raeann would spend the same amount.

0.7 u = 0.4 u + 0.8 + 1.3
0.7 u - 0.4 u = 0.8 + 1.3
0.3 u = 2.1

1 u = 2.1 ÷ 0.3 = 7

Number of pomegranates that Emily bought
= 1 u + 2
= 7 + 2
= 9

(b)
Amount that Raeann spent on the peaches
= 0.7 u 
= 0.7 x 7 
= $4.90

Answer(s): (a) 7; (b) $4.90
