Question

If 4 cookies cost a dollar, then how much will 24 cookies cost?

Answer 1

Given: The cost of 4 cookies is a dollar

To Determine: The cost of 24 dollars

Calculate the cost of 1 cookie

`\begin{gathered} 4N_{\text{COOKIES}}=1\colon N_{\text{COOKIE}}=\text{number of cookies} \\ 1N_{\text{COOKIE}}=(1)/(4)=0.25 \end{gathered}`

Calculate the cost of 24 cookies

`\begin{gathered} 24N_{\text{COOKIES}}=24*(1)/(4) \\ 24N_{\text{COOKIES}}=6 \end{gathered}`

Hence, the cost of 24 cookies is $6
