Sophia buys a mixed bunch of flowers for $15. Then she buys roses for $3 each and tulips for $2 each.
Write an algebraic expression that can be used to find the total number of money Sophia will spend
on flowers if she buys any number of roses, r, and any number of tulips, p.
Then find the total amount of money Sophia will spend on flowers if she buys 7 roses and 4 tulips.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

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 %
