A printing company uses the formula C=0.5x+10 to find the cost of printing x business cards which equation correctly solves the formula for x?

C=0.5x + 10

Where:

C = total cost of printing

x = number of business cards printed

0.5 = variable cost of printing, this cost depends on the number of business card

10 = fixed cost of printing, this cost stays the same regardless of the number of business card printed.

C = 0.5x + 10; derive the formula of x.

C - 10 = 0.5x

(C - 10) / 0.5 = x
