The online price for a box of hair clips is $2.60. For any number of boxes purchased, the cost of shipping is $12. The equation c=2.60b + 12 represents the total cost, c, of ordering b boxes of hair clips. If Mrs. Hilton orders 32 boxes of hair clips, what is the total cost? (6.EE. C.9)

Step-by-step explanation:

Step one:

given data

the total cost function is

c=2.60b + 12

Step two:

Required is c, when b= 12

substitute b=12 we have

c=2.60(12) + 12

c=31.2+ 12

c=43.2

the total cost = $43.2

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 %  

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
