Please select the best answer from the choices provided

D, C, B, A

Step-by-step explanation:

Given the prices below:

Store A: price $99.99 and discount of 15%

15% discount :

Discounted price : (1 - 0.15) * $99.99 = $84.99

Store B: price $95.99 and discount of 12%

12% discount :

Discounted price : (1 - 0.12) * $95.99 = $84.47

Store C: price $90.99 and discount of 10%

10% discount :

Discounted price : (1 - 0.10) * $90.99 = $81.89

Store D: price $89.99 and successive discounts of 5% and 5%

5% discount :

Discounted price : (1 - 0.05) * $89.99 = $85.4905

5% discount :

(1 - 0.05) * $85.4905 = $81.22

Cheapest = store D, then then C, then B, then A

too hard the other guy did it

step-by-step explanation:

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
