A fruit stall sold oranges at 60¢ and peaches at 30¢ each. Yen bought some oranges and Emily bought some peaches from the stall. Yen spent $2.40 more than Emily, but had 2 fruits fewer than Emily.

1. How many oranges did Yen buy?
2. How much did Emily spend on the peaches?

	Oranges	Peaches
Number	1 u	1 u + 2
Value	0.6	0.3
Total value	0.6 u	0.3 u + 0.6

(a)
Number of oranges that Yen bought = 1 u
Number of peaches that Emily bought = 1 u + 2

Amount that Yen paid = 0.6 x 1 u = 0.6 u
Amount that Emily paid = 0.3(1 u + 2) = 0.3 u + 0.6

If Emily spent another $2.40, both Emily and Yen would spend the same amount.

0.6 u = 0.3 u + 0.6 + 2.4
0.6 u - 0.3 u = 0.6 + 2.4
0.3 u = 3

1 u = 3 ÷ 0.3 = 10

Number of oranges that Yen bought
= 1 u
= 10

(b)
Amount that Emily spent on the peaches
= 0.3 u + 0.6
= 0.3 x 10 + 0.6
= 3 + 0.6
= $3.60

Answer(s): (a) 10; (b) $3.60
