Answer:
she makes $6.676 an hour
Step-by-step explanation:
402.17-93.26-41.86=267.05/40=6.67625
There are 20 gallons of 20% butterbeer solution.
Assume there are x gallons of 80% solution.
So total amount of the solution will be (x+20) gallons
The final solution is 50%.
So, we can set up the equation as:
.
Thus, there will be 20 gallons of 80% butterbeer solution that is needed to be mixed with 20 gallons of 20% butterbeer solution.
Given:
product of 2 numbers is 450.
first number is half the second number.
Let us make our own equation based on the given data.
Let x and y be the two numbers.
y * x = 450
y is the 1st number. It is said that it is half the second number, x.
y = 1/2 * x = x/2
Let us substitute y of the 1st equation by its value in the second equation.
x/2 * x = 450
x² / 2 = 450
x² = 450 * 2
x² = 900
√x² = √900
x = 30
The value of x, the 2nd number, is 30.
y = x/2 = 30/2 = 15
The value of y, the 1st number, is 15.
To check:
y * x = 450
15 * 30 = 450
450 = 450
