Linda should use ...
15 gallons of 80% juice
5 gallons of 60% juice
_____
Let g represent the number of gallons of 80% juice needed. Then (20-g) is the number of gallons of 60% juice Linda will use. The amount of juice in the mixture can be written as
0.80g +0.60(20 -g) = 0.75×20
0.20g = 20(0.75 -0.60) = 20×0.15
g = 20×0.15/0.20 = 15
The amount of 80% juice needed is 15 gallons, so 5 gallons of 60% juice are needed.
Answer: There are 7 students who want French only.

Similarly,
Hence, there are 7 students who want French only.
Answer:
Step-by-step explanation:
Hi there! The answer is 61.5 square feet.
The area of a rectangle can be found using the formula:
A = L × W = length × width
The area of the floor is
12 × 10 = 120 square feet.
The area of the rug is
6.5 × 9 = 58.5 square feet.
The area of the floor that is not covered by rug is
120 square feet - 58.5 square feet =
61.5 square feet.
The answer is 61.5 square feet.
