We have 12 liters of 8% acid solution to which we add an unknown amount of liters (x) of 20% acid solution to make a 16% acid solution.
.08 * 12 +.20x = .16 * (12 +x)
.96 + .20x = 1.92 + .16x
.04x = .96
x = 24 liters of 20% acid solution must be added

Mrs. Tomas is installing a fence around the perimeter of her garden. The perimeter of the garden is 36 feet. Each section of the
WITCHER [35]

Answer:

C = (36/3)* $24

C = $288

Step-by-step explanation:

In this question, we are asked to write an equation for cost c of the section of fence needed for the garden and the solve for the value c.

C is already assigned as the cost of the sections she needs for her garden.

We were made to understand that the perimeter of the garden is 36 feet, with a 3 feet each section. Now, what we need to do is to know the number of sections that we have. Since, each section is 3 feet, and the total perimeter is 36 feet, this means that the total number of sections needed would be 36/3. Each of the section as we were told costs $24, so we can then proceed to calculate the value of C from there.

C = (36/3)* $24

This is the equation that gives the cost. The actual value of the cost is thus:

C = 12 * 24 = $288

The total cost of the sections if the Fence is $288
