Explanation:

Step1: Identify the operation

To find the number of cookies left, we subtract the number of cookies eaten from the total number of cookies bought. The formula is: $Cookies\ left = Total\ cookies - Cookies\ eaten$.

We know the total number of cookies is 45 and the number of cookies eaten is 28. So we calculate $45 - 28$.
