Answer to Problem 16IP

  $\frac{d}{7}+4$

Explanation of Solution

Given:

The number of inches in any number of feet.

In order to translate the phrase into an algebraic expression. Four more than the number of weeks in a group of days, let d be the group of days, then to convert days into weeks divide the number of days into 7 because there are 7 days in a week, and then add 4 because it states that it is 4 more than the number of weeks in a group of days, as shown below:

  $\frac{d}{7}+4$

So, the algebraic expression is $\frac{d}{7}+4$ .
