Question

Estimate A store sells 16 cookies for $11.88. Estimate the cost per cookie. Explain how you made your estimate.

Short answer

The cost per cookie is $0.7425.

Step-by-step solution

. Given

Given that the cost of 16 cookies = $11.88.

. To determine

We have to find the cost per cookie.

. Calculation 

In order to calculate the cost per cookie we will find the unit rate. Given that the cost of 16 cookies is $11.88.

So the cost of one cookie will be:

$\frac{\$11.88}{16\text{cookies}}$

To find the unit rate we will make the denominator = 1.

$\begin{array}{l}\frac{\$11.88÷16}{16\text{cookies}÷16}\text{[Dividenumeratoranddenominatorby}16\text{]}\\ \frac{\$0.7425}{1\text{cookie}}\end{array}$

So, the cost per cookie is $0.7425.
