Let
x: amount of pounds of cheese that Bill can buy.
We can write the following inequation for this problem
x <= 1/2
Therefore, Bill could buy up to 1/2 pound of cheese.
answer
1/2 pound of cheese (maximum)
My teacher taught me a simple equation for these types of problems:
(percent of solution × amount of solution) + (percent of solution × amount of solution) = (percent of solution × total amount of solution)
in simple terms: %amount + %amount = %total amount
We know don't know how much gallons of 60% solution we need so it will be represented as x. We dont know the total amount either so it would have to be both solutions added together so 50 + x. Now lets solve:
(0.60)(x) + (0.24)(50) = (0.50)(50 + x) simplify/ distribute
0.6x + 12 = 25 +0.5x get all xs on one side and numbers on other
0.1x + 12 = 25
0.1x = 13 divide both sides by 0.1 to find x
x = 130
You need 130 gallons of 60% solution.

5n+ 5= 17
5n= 17-5
5n= 12
N= 12/5
N= 2.4
The answer is 2.4.
