Assignments and Methods of Evaluating Student Progress:
1. Typical Assignments
a. The Coffee Shoppe sells a coffee blend made from two coffees, one costing $2.50/lb. If the blended
coffee sells for $2.80/lb, find how much of each coffee is used to obtain the desired blend. (Assume
the weight of the blended coffee is 100lb.)
b. Find how much money should be deposited in a bank paying interest at the rate of 8.5% per year
compounded quarterly so that at the end of five years the accumulated amount will be $40,000.
