30% =
30100 =
310Number of pomegranates = 3 u
Number of mangosteens = 10 u - 3 u = 7 u
Price of each pomegranate in percent = 100%
Price of each mangosteen in percent = 100% + 40% = 140%
Price of each mangosteen
= 2.50 x 140%
= 2.50 x
140100 = $3.50
7.5 u + 24.5 u = 416
32 u = 416
1 u = 416 ÷ 32 = 13
Cost of the pomegranates
= 3 u x 2.50
= 3 x 13 x 2.50
= $97.5
(b)
Number of mangosteens ordered
= 7 u
= 7 x 13
= 91
Answer(s): (a) $97.5; (b) 91
