Oth John's parents and Marco's parents decide to start a college fund for their children. The expressions below represent the value of each college fund after w weeks. John's College Fund: 43 w + 1814 12 Marco's College Fund: 25 w + 1744

Step-by-step explanation:

The question is not clear on what to solve for, but we can solve for the number of weeks in which the two funds will have the same amount.

let the total fund funds be y

and the number of weeks be w

For John's fund the expression is

y=45w+18141

Marco's College Fund

y=25 w+17442

equating 1 and 2 we have

45w+1814=25w+1744

45w-25w=1744-1814

20w=-70

divide both sides by 20 we have

w=-70/20

w=-3.5

this means that in 3 and half weeks the two funds will have the same amount in them

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
