The cost, in dollars, of a one-day car rental is given by c(x) = 31 0.18x, where x is the number of miles driven. in this function,
a.$0.18 is the cost per day to rent the car and $31 is the cost per mile.
b.$31 is the cost per day to rent the car and $0.18 is the cost per mile.
c.$18 is the cost per day to rent the car and $0.31 is the cost per mile.
d.$31 is the cost per day to rent the car and $18 is the extra cost for unlimited miles.

Hello mate!

the function is c(x) = 31 + 0.18*x

where $31 is a fixed cost, and $0.18 is the cost per mile drive (where the number of miles driven)

So the fixed cost, $31, is the cost per day of rent (this price does not depend on the number x), and the linear cost, $0.18, is the cost per mile driven (because this number is multiplied by x in the function), then the right answer is B: "$31 is the cost per day to rent the car and $0.18 is the cost per mile."

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 %
