Question

Marcy needs 150 feet of fabric for her project. She uses 20% of it. How many feet of fabric did she use for her project so far? You may use a bar model or double number line.

Answer 1

30 feet.

Explanation:

Steps

First, convert the percentage discount to a decimal. 20 percent of 150 is 0.20 in decimal format.

Secondly, multiply the decimal discount by the price of the item to determine the savings in dollars.

In this case, the original fabric needed equals 150 feet, you would multiply 0.2 by 150 to get the answer.

Solution

20 percent *150 =

(20:100)*150 =

(20*150):100 =

3000:100 = 30

Therefore, she used 30 feet for her project so far.

Answer 2

The answer is 120 feet of fabric
