Question

ok here is the question I got half of it so here it is
If gasoline costs $1.23 per gallon, how much would it cost to buy 12.5 gallons
It costs 14.76 for 12 gallons
but what do I do for the .5 part ?

Answer 1

okay so x= # of gallons
here is an equation. y=1.23x
if x=number of gallons and it says to buy 12.5 gallons you would sub. in 12.5 in for x and get
y=(1.23)(12.5) do you have a calculator or do it by hand?
