A fruit vendor ordered some fruits. 35% of the fruits he ordered were passion fruits and the rest were starfruits. Each passion fruit cost $2.50 and each starfruit cost 40% more than each passion fruit. The vendor paid a total of $504.

1. Find the total cost of the passion fruits.
2. How many starfruits did he order?

(a)

	Passion Fruits	Starfruits
Numbers	7 u	13 u
Price	$2.50	$3.50
Total value	17.5 u	45.5 u

35% = ³⁵₁₀₀ = ⁷₂₀

Number of passion fruits = 7 u
Number of starfruits = 20 u - 7 u = 13 u

Price of each passion fruit in percent = 100%
Price of each starfruit in percent = 100% + 40% = 140%

Price of each starfruit
= 2.50 x 140%
= 2.50 x ¹⁴⁰₁₀₀
= $3.50

17.5 u + 45.5 u = 504
63 u = 504
1 u = 504 ÷ 63 = 8

Cost of the passion fruits
= 7 u x 2.50
= 7 x 8 x 2.50
= $140

(b)
Number of starfruits ordered
= 13 u
= 13 x 8
= 104

Answer(s): (a) $140; (b) 104
