Question

Markia had some cookies. She gave four to her sister. Then, she divided the remainder into two halves, and she still had five cookies left.

Answer 1

14

Explanation:

x-4= no. of cookies that she had after giving 7 to her sister

`(x-4)/(2)` after dividing the remaining half.

Times two to get rid of the denominator:

x-4=10

x=14

Markia had 14 cookies to start.

Answer 2

Markia had 14 cookies.

Explanation:

Let's represent the total amount of cookies as y.

We know that after she gave away 4 cookies and divided the remainder by 2, she had 5 cookies left.

This can represented as an equation.

`(y - 4)/(2)` = 5

To solve this equation we have to isolate the y.

`(y - 4)/(2)` = 5

Multiply both sides by 2 to isolate the y - 4: y - 4 = 10

Add 4 to both sides to isolate the y: y = 14

The total amount of cookies is 14.
