Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make it a 12% detergent solution. which equation can she use to find g, the number of gallons of water she should add? a. 1.98/11+g - 12/100 = 1 b. 1.98/11+g + 12/100 = 1 c. 11+g/1.98 = 12/100 d. 1.98/11+g = 12/100

The problem is about adding water to detergent solution to make a detergent solution.

In the problem g is taken for the number of gallons of water.

So, we can rephrase the given problem in simple words as

g gallons of water is added to  11 gallons of 18% detergent solution to get 12% detergent solution.

Let us write it in form of an equation,

g gallons of water is being added to 11 gallons of solution.

The total amount of solution will be (11 + g) gallons.

11 gallons of 18% detergent solution = 12% detergent solution.

For percent we can write over 100.

Therefore, above equation can be written as

11 × 18/100 = 12/100(g+11)

11 time 18 = 198

Therefore,

198/100 = 12/100(g+11)

Converting 198/100 into decimals, we get 1.98

We can rewrite above eqaution as

1.98 =12/100(g+11)

Dividing both sides by (g+11), we get

Therefore, correct option is D. 1.98/11+g = 12/100.
