Question

Alex’s gasoline consumption, g, varies inversely with the price of a gallon, p. Alex uses 22 gallons of gas per week when the price is $3.49 per gallon. How many gallons will he use if the price goes up to $3.89 per gallon? Round to the nearest gallon.

Answer 1

This time, inversely varying implies product of the two is a constant.
So,
\[22 \times 3.49 = g \times 3.89\]
Find g the number of gallons.
