Question

Kelly is making a bubble mixture for kids to play with at a backyard party. She adds 1/4 of a cup of corn syrup to 6 cups of soap and water.

She wants to make more bubble mixture and has 18 cups of the soap and water mixture to use.

How much corn syrup does she need to add?

A. 2/3 of a cup of corn syrup
B. 3 cups of corn syrup
C. 3/4 of a cup of corn syrup
D. 3 1/4 cups of corn syrup

Answer 1

Answer: C. 3/4 of a cup of corn syrup

Explanation:

We will set up a proportion to help us solve.

`\displaystyle \frac{1/4\text{ cup corn syrup}}{6\text{ cups of soap and water}} =\frac{x\text{ cups corn syrup}}{18\text{ cups of soap and water}}`

Next, we will cross-multiply.

1/4 * 18 = 6 * x

9/2 = 6x

Lastly, we will divide both sides of the equation by 6.

x = 3/4 of a cup of corn syrup

C. 3/4 of a cup of corn syrup
