Question

the total cost for printing ( x ) copies of a book is $200 plus $2.50 per copy. which equation represents the total cost (( c ))?
a. ( c = 200 + 2.50x )
b. ( c = 200x + 2.50 )
c. ( c = 200 \times 2.50 )
d. ( c = 200 - 2.50x )

Explanation:

Step1: Identify fixed and variable costs

Fixed cost = $200; variable cost = $2.50 per copy (\(x\))

Step2: Form total cost equation

Total cost = fixed cost + (variable cost × number of copies) → \( C = 200 + 2.50x \)

Answer:

a. \( C = 200 + 2.50x \)
