Question: Estimate and calculate the total number of individual packages of variety chips purchased, given that 18 packages of 42-count variety chips were bought. Answer: The estimated total number of individual packages purchased is 720, while the actual total number is 756.

Step-by-step solution

Estimating the Total Number of Packages Purchased

In the problem, we are given that we purchased eighteen 42-count packages of variety chips. To estimate this, we will round the number 42 to the nearest ten, which is 40. Now, we multiply the rounded number (40) by the number of packages purchased (18) to get the estimated number of individual chips purchased: $$ 18\times 40 = 720 $$ Thus, our estimation for the total number of individual packages purchased is 720.

Calculating the Actual Total Number of Packages Purchased

To calculate the actual number of individual packages purchased, we will use the given number in the problem, which is 42-count packages. Now, we multiply the actual number of variety chip packages in each package (42) by the number of packages purchased (18) to get the actual number of individual chips purchased: $$ 18\times 42 = 756 $$ Thus, the actual total number of individual packages purchased is 756.
