Question 1199161: Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $29 monthly fee and charges an additional $0.15 for each minute of calls. The second plan has a $19 monthly fee and charges an additional $0.19 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal? Answer by ikleyn(52781) (Show Source):
Write the money expression for each company and equate these expressions
29 + 0.15m = 19 + 0.19m,
where "m" is the number of minutes.
Simplify this equation and find the unknown quantity "m".
