Answer: 35%
Step-by-step explanation:
Let the original price be "4x".
60% gain on 1/2 of them will be:
(1.60 × 2x) = 3.2x - 2x = 1.2x
20% gain on (1/4) of them will be:
(1.2 × x) = 1.2x - x= 0.2x
Total gain 1.2x + 0.2x = 1.4x
Total gain percent= Gain/Original price =1.4x/4x = 0.35 = 35%
Answer:
2520 patterns
Step-by-step explanation:
In 'n' 10! ways, books can be arranged. But, there are also 5! permutation of blue books 'n1', 2! permutation of identical green books 'n2', and 3! permutation identical black books 'n3'.
Therefore, for non identical arrangements:

= 2520
Therefore, the books can be arranged on a shelf in 2520 patterns
The total gallons of sports drink Jaylen made using 9/10 of a large cooler with water and 6 cups of sports drink concentrate is 3.75 gallons
<h3>Total gallons</h3>
- Water in the large cooler = 9/10
Space remaining = 1 - 9/10
= 10-9 / 10
= 1/10
1/10 = 6 cups
- Total gallons of sport drink = x
6 cups / total = 1/10
6 × 10 = total × 1
60 cups = total
Cups to gallons:
16 cups = 1 gallon
Total gallons of sport drink, x = 60 cups / 16
= 3.75 gallons
