A fruit stall sold dragon fruits at 70¢ and peaches at 40¢ each. Anna bought some dragon fruits and Rachel bought some peaches from the stall. Anna spent $1.30 more than Rachel, but had 2 fruits fewer than Rachel.

1. How many dragon fruits did Anna buy?
2. How much did Rachel spend on the peaches?

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

(a)
Number of dragon fruits that Anna bought = 1 u
Number of peaches that Rachel bought = 1 u + 2

Amount that Anna paid = 0.7 x 1 u = 0.7 u
Amount that Rachel paid = 0.4(1 u + 2) = 0.4 u + 0.8

If Rachel spent another $1.30, both Rachel and Anna 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 dragon fruits that Anna bought
= 1 u
= 7

(b)
Amount that Rachel spent on the peaches
= 0.4 u + 0.8
= 0.4 x 7 + 0.8
= 2.8 + 0.8
= $3.60

Answer(s): (a) 7; (b) $3.60
