If the total cost of all five meals was $51.94 which included a 6% sales tax, what was the cost of one meal before tax was added?

259.7

Step-by-step explanation:

hope this helps!

$9.80

Step-by-step explanation:

An easy way to work out the original cost is to do this:

The total cost of all meals is 100%.

If we know the percentage added on top of that is 6%, we know the total is now 106% of the original price.

To work out what the original price is, divide the current amount by 106.

This gives you $0.49, then divide that by 100.

This will give you $49, which is the original cost of the meals without the 6%.

If the meals are all priced the same, dividing $49 by 5 will give you $9.80.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

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
