A store sells 25 items per day. If the store has sold 200 items, how many days has it been selling (d)? Write an equation and solve for the variable.
To solve this problem, let's define the variable: d represents the number of days that we need to find.
The relationship between the total number of items sold, the number of items sold per day, and the number of days is given by:
Total items sold = Items sold per day × Number of days
Given:
Total items sold = 200
Items sold per day = 25
