Cost Analysis

Fill in the Blanks

A government estimates the cost to design new radar technology over a period of "m" months. The government estimates $840,000 for equipment, $15,000 for software, and $40,000 per month for wages. Use an algebraic expression to find the total cost the government estimates when the project takes 16 months to complete.
