A homeowner is planning to build a concrete sidewalk that will require 1 3/4 cubic yards of concrete. She also will build a small patio requiring 2 1/3 cubic yards of concrete. The two projects are in the backyard, so the concrete will be carried in a wheelbarrow. The wheelbarrow will comfortably hold 1/6 of cubic yard of concrete. How many wheelbarrow loads will be required for the entire job?

Question 2

David Riley owns a five-year-old computer game business. Because of slack business, David needs to borrow 25,000 . Compute the interest fee if David gets the loan for 120 days at 12 ordinary simple interest. (Use a 360-day year.)

Answer to Question 1

Total cubic yards: 1 3/4 + 2 1/3 = 7/4 + 7/3 = 21/12 + 28/12 = 49/12
Number of wheelbarrow loads: 49/12 1/6 = 49/12  6 = 49/2 = 24 1/2

Answer to Question 2

25,00 .  0.12  120/360 = 1,000
