Algebra 1 – Unit 2 Review Phyllis the plumber is a busy lady. For service calls to homes she uses the following formula to figure out how much to charge for her labor (materials are extra of course): c = 40n + 60 where c is the amount she charges and n is the number of hours she works. What is the meaning of 40 in the formula above? What is the meaning of 60 in the formula above?
