Bobby goes to one store and finds a Christmas tree for $49.99. The store is having a 20% off sale. Bobby decides to go across the street to another store and finds the same tree for $54.99. This store is having a 25% off sale. What is the difference in the sale prices for the tree?

1.24

Step-by-step explanation:

first multiply 20% and 49.99= 10

subtract 10 from 49.99= 40

multiply 25% and 54.99= 13.75

subtract 13.75 from 54.99= 41.24

subtract 41.24 and 40= 1.24

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

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
