Mrs. Ruiz bought 6 gallons of gas for $18.18, 9 gallons of gas for $27.27, and 16 gallons for $48.48. Is the rate of change constant?

one gallon is 3.03 dollars. I don't know is that helps.

Step-by-step explanation:

18.18/6=3.03

27.27/9=3.03

48.48/16=3.03

62.93

Step-by-step explanation:

add the money and subtract it from the gallons

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
