1 Proper Formulas Bethany Fargher Instructor: Layla Hedayat MAT126: Survey of Mathematical Methods July 4, 2011 For this assignment I will be taking story problems and answering them. These story problems when reading them seem to be really simple to solve. I solved them in my head but I have to show my work which to me is really hard but I found an easy way to show it. 35 . A person hired a firm to build a CB radio tower. The firm charges $100 for labor for the first 10 feet. After that, the cost of the labor for each succeeding 10 feet is $25 more than the preceding 10 feet. That is, the next 10 feet will cost $125; the next 10 feet will cost $150, etc. How much will it cost to build a 90-foot tower?

At the end of 10 years, how much money will be in the savings account? Solve: You take 500 and multiply the 5% which would be 0.05 and you get 25. That is one year of interest. Then you take 25 and multiply 10 and you would get 250 then add your 500 and you get the answer of 750. (Mathematics in Our World. McGraw-Hill Create p. 282). <vbk:9780390671455#page(282)>...
