Provide an appropriate response. A catalog company is considering the purchase of an 800 phone number. Without the 800 number, calls cost $0.22 per minute, and with the 800 number calls will cost $0.13 per minute plus a $55.00 flat rate. Write a symbolic statement that could determine the minutes of calls that would make the $0.22 per minute charge equal to a $0.13 per minute charge including the $55.00 flat rate.
A. 0.22 = 0.13 + 55.00x B. 0.22x = 0.13 + 55.00x C. 0.22x = 0.13x + 55.00 D. 0.22x + 55 = 0.13x
