Answer:
6 oz
Step-by-step explanation:
if 10 oz = 20%
1oz = 5%
50%-20%=30%
30/5=6
6oz
The amount of water that must be evaporated to make a 50% solution is 6 ounces.
What is an Equation?
A statement that represents the equality of two algebraic expressions is called an equation.
The syrup John has is 10 ounces of 20%
The syrup he wants is 50%
Let x amount of water is evaporated, then the total amount of syrup should be 50% of the final solution.
(50/100) * (10 -x) = 2
10- x = 4
x = 6
Therefore, the amount of water evaporated is 6 ounces.
