if you can buy 8 gallons of gas for $25.60, what is the cost per gallon? use a proportion to slove and show all work

Set up a proportion:

 8 gallons                    1 gallon

     =    

 25.60 dollars              x dollars

Then, cross multiply

8x= 25.60

x = 3.20 dollars

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
