$C(5) +\int _ { 5 } ^ { 31 } C ^ { \prime } ( t ) d t= 25,000$ , where $C$ represents calculator sales during the month of August and $t$ represents the day of the month. In the context of the problem, write a complete description about what the integral is computing. Use correct units and be sure to mention the meaning of the bounds in your description.

Recall that definite integrals can be considered accumulation functions.
What does $C^\prime$ represent? What is being accumulated?

$25,000$ calculators were sold (accumulated) between August 1st and August 31st.
