80% of the caramel apples in Packet B were vanilla caramel apples and the rest were banana caramel apples. Packet C had 30% more vanilla caramel apples than Packet B and twice as many caramel apples than the total number of caramel apples in Packet B. Find the percentage of the banana caramel apples in Packet C that would need to be transferred into Packet B, so that there were an equal number of vanilla and banana caramel apples in Packet B.

	Packet B		Packet C
	Vanilla	Banana	Vanilla	Banana
	5 u		10 u
Before	4 u	1 u	5.2 u	4.8 u
Change		+ 3 u		- 3 u
After	4 u	4 u	5.2 u	1.8 u

80% = ⁸⁰₁₀₀ = ⁴₅
100 %+ 30% = 130%

 Total number of caramel apples in Packet B
= 4 u + 1 u
= 5 u

Total number of caramel apples in Packet C
= 2 x 5 u 
= 10 u

Number of vanilla caramel apples in Packet C
= 130% x 4 u
=  ¹³⁰₁₀₀ x 4 u
= 5.2 u

Number of vanilla caramel apples in Packet C
= 10 u - 5.2 u
= 4.8 u

Number of banana caramel apples to be transferred from Packet C to Packet B
= 4 u - 1 u
= 3 u

Percentage of caramel apples to be transferred from Packet C
= ³_4.8 x 100%
= 62.5%

Answer(s): 62.5%
