A stationary store sells staplers for 1.50 dollar each. A company buys an unknown number of these staplers at a cost of 36.00 dollar in total. How many staplers did the company purchase?

Let N represent the number of staplers purchased.
Set Up an Equation.
1.50N = 36.00
To isolate an unknown value N, divide both sides of the equation by 1.50.
\(\frac{\mathrm{1.50N } }{\mathrm{1.50}} = \frac{\mathrm{36.00 } }{\mathrm{1.50}}=24\)
The business purchased 24 staplers.
