310Number of lemons = 3 u
Number of dragonfruits = 10 u - 3 u = 7 u
Price of each lemon in percent = 100%
Price of each dragonfruit in percent = 100% + 50% = 150%
Price of each dragonfruit
= 2.60 x 150%
= 2.60 x
150100 = $3.90
7.8 u + 27.3 u = 702
35.1 u = 702
1 u = 702 ÷ 35.1 = 20
Cost of the lemons
= 3 u x 2.60
= 3 x 20 x 2.60
= $156
(b)
Number of dragonfruits ordered
= 7 u
= 7 x 20
= 140
Answer(s): (a) $156; (b) 140
