A person hired a firm to build a CB radio tower, the firm charges $100.00 for labor for the first 10 feet, after that the cost of the labor for each succeeding 10 feet is $25.00 more than the preceding 10 feet. That is, the next 10 feet will cost $125.00 the next 10 feet will cost $ 150.00 etc. How much will it cost to build a
