On each flight, an airplane is filled with 10 quarts of oil. The airline adds an additional (1/2) quart of oil for each planned hour of flying. Write an equation that can be used to determine the planned flying time, h , in hours, for an air plane filled with 13 quarts of oil.

1. Scott

h=(q-10)*.5

2. Steve

oil = 10 + 1/2 h

13 = 10 + h/2
3 = h/2
6 = h
