Robert is purchasing some equipment for his baseball team. he wants to buy some baseballs, each priced at m dollars. he has already spent b dollars on other equipment. the following expression represents the total amount robert will spend after buying x baseballs.

For this case, the first thing we must do is define variables.

We have then:

x: number of baseballs

y: total amount

We know that each baseball costs $ m.

We also know that Robert has spent $ b.

Therefore, the expression that models the problem is given by:

The following expression represents the total amount Robert will spend after buying x baseballs:

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 %
