Question

Zara purchased a sealed package of cookies and ate 25% of them. Her cousin ate the remaining 18 cookies. How many cookies were in the sealed package?

Answer 1

24

Explanation:

Zara ate 25% of the cookies.

100% - 25% = 75%

Zara left 75% of the cookies.

Her cousin ate 18 cookies.

That means that 75% of the cookies is 18 cookies.

Let x = original number of cookies.

75% of x = 18

0.75x = 18

Divide both sides by 0.75

x = 18/0.75

x = 24

Answer: 24
