25Number of mangosteens = 2 u
Number of kiwis = 5 u - 2 u = 3 u
Price of each mangosteen in percent = 100%
Price of each kiwi in percent = 100% + 50% = 150%
Price of each kiwi
= 2.40 x 150%
= 2.40 x
150100 = $3.60
4.8 u + 10.8 u = 78
15.6 u = 78
1 u = 78 ÷ 15.6 = 5
Cost of the mangosteens
= 2 u x 2.40
= 2 x 5 x 2.40
= $24
(b)
Number of kiwis ordered
= 3 u
= 3 x 5
= 15
Answer(s): (a) $24; (b) 15
