Question

Cost of production of each unit of electricity is 3 less than twice the total number of units produced. The expression for total cost of production is

• A. x(2x+3); where x is the total number of units
• B. x(2x-3); where x is the total number of units
• C. x(3x+2); where x is the total number of units
• D. x(3x-2); where x is the total number of units

Answer 1

The correct option is B

x(2x-3); where x is the total number of units

Let the number of units produced be ‘x’

Cost of production of each unit of electricity = 2x-3

Total cost of production = x(2x-3)
