A fruit stall sold apricots at 60¢ and peaches at 30¢ each. Natalie bought some apricots and Tiffany bought some peaches from the stall. Tiffany spent $1.20 less than Natalie, but had 4 fruits more than Natalie.

1. How many peaches did Tiffany buy?
2. How much did Natalie spend on the apricots?

	Apricots	Peaches
Number	1 u	1 u + 4
Value	0.6	0.3
Total value	0.6 u	0.3 u + 1.2

(a)
Number of apricots that Natalie bought = 1 u
Number of peaches that Tiffany bought = 1 u + 4

Amount that Natalie paid = 0.6 x 1 u = 0.6 u
Amount that Tiffany paid = 0.3(1 u + 4) = 0.3 u + 1.2

If Tiffany spent another $1.20, both Tiffany and Natalie would spend the same amount.

0.6 u = 0.3 u + 1.2 + 1.2
0.6 u - 0.3 u = 1.2 + 1.2
0.3 u = 2.4

1 u = 2.4 ÷ 0.3 = 8

Number of peaches that Tiffany bought
= 1 u + 4
= 8 + 4
= 12

(b)
Amount that Natalie spent on the apricots
= 0.6 u 
= 0.6 x 8 
= $4.80

Answer(s): (a) 8; (b) $4.80
