A botanist collects and models some data and is able to determine that the number of germinated seeds of a certain plant is linearly correlated to the amount of rainfall during the previous month, according to the equation s = 28.5r + 83. In this equation, s is the number of seeds germinated and r is the amount of rainfall in inches. In a certain geographic region that the botanist is studying, 197 seeds germinated. Approx. how many inches of rainfall did that area receive during the previous month?

A publishing company ships books to schools, some of which are hardcover textbooks and some of which are paperback workbooks. Each shipping box can hold a max of 20 textbooks or 64 workbooks. Each textbook is 192 cubic inches of space and each workbook is 60. One box holds a max of 3,840 cubic inches. The shipping dept. is packing a box containing both types of books. What are the three inequalities you should make in order to solve this problem?

t =< 20       w =< 64        192t + 60w =< 3,840

Car manufacturers have started producing hybrid vehicles which run on both electricity and gas, resulting in a significantly higher gas mileage. Suppose the odometer of a hybrid car, which shows how many miles the car has traveled, reads 4,386 miles. If the car averages 48 miles to the gallon of gas and currently has 12 gallons in the tank, what should the odometer reading be when the tank is empty?
