Question

The Parker family bought 6 bags of cookies. Each bag had 14 cookies. They have since eaten 29 of the cookies. How many cookies do they have left?

Answer 1

Given

Number of bags the family bought = 6 bags

Each bag has 14 cookies

They had eaten 29 of the cookies

The total number of cookies available in the 6 bags can be found using the formula below:

`Total\text{ number of cookies = Number of bags }*\text{ cookies per bag}`

Substituting the given values:

`\begin{gathered} Total\text{ number of cookies = 6 }*\text{ 14} \\ =\text{ 84 cookies} \end{gathered}`

Let the number of cookies they have left be x

The number of cookies left is the difference between the total number of cookies and the number they have eaten

`x\text{ = Total number of cookies - Number of cookies eaten}`

Substituting we have:

`\begin{gathered} x\text{ = 84 - 29} \\ =\text{ 55 cookies} \end{gathered}`

Hence, they have 55 cookies left
