A bus uses 1 gallon of diesel for every 7 miles traveled. The amount of
diesel left in the gas tank, p gallons, after traveling q miles, is given by
q = 112 − 7p. Copy and complete the table. Graph the relationship
between p and q. Use 1 unit on the horizontal axis to represent 1 gallon
and 1 unit on the vertical axis to represent 7 miles.

A. How many gallons of diesel were left after the bus has traveled 49 miles?
B. After the bus has traveled for 56 miles, how much farther can the bus
travel before it runs out of diesel?
C. If the bus travels more than 28 miles, how much diesel is left?
Express your answer in the form of an inequality in terms of p,
where p stands for the amount of diesel left.
