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

help please

Answer 2

when p goes up g goes down= inverse proportion so

g1P1= g2P2

g1*P1/P2 = g2
so
22(3.49) \3.89 = gallons used at new price

Answer 3
