You have stopped adding any additional charges to this card and are determined to pay off the balance. You have worked out the formula bbn = b0r n − R(1 + r+r2 +....+ r n−1), where b0 is the initial balance, bn is the balance after you have maden payments, r= 1 + i, wherei is the monthly interest rate, and R is the amount you are planning to pay each month.b. Explain why we can rewrite the given formula as bn= b0rn − R(1-rn/1-r).????????

Answer:

$1+r+r^(2)+r^(3)+.....+r^(n-1) = (1-r^(n))/(1-r)$

Step-by-step explanation:

Taking the succession:

$1+r+r^(2)+r^(3)+.....+r^(n-1)$

You can multiply and divide by 1-r without chaging the result:

$(1-r)/(1-r) (1+r+r^(2)+r^(3)+.....+r^(n-1))$

Distributing the upper part of the fraction you have:

$(1)/(1-r) (1-r+r-r^(2)+r^(2)-r^(3)+r^(3)-r^(4)+.....+r^(n-1)-r^(n))$

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only $(1-r^(n))$ will be left so:

$1+r+r^(2)+r^(3)+.....+r^(n-1) = (1-r^(n))/(1-r)$

Please help will give brainliest!CheapBuys, a large bulk store, sells cases of bottled water for $13.49. There are 48 bottles in each case and the bottles are 12 ounces each. Sarah remembers that the vending machine at work sells the same size bottle for $0.75 per bottle. Calculate the cost for one bottle and tell if Sarah should buy bottled water by the case or not.

A: Buying in bulk will not save her any money since the bottles in the case and the bottles from the vending machine are both about 75 cents each.

B: The cost per bottle at CheapBuys is approximately 28 cents, so Sarah will save a considerable amount of money by buying water in bulk rather than from the vending machine.

C: Each bottle of water in the case from CheapBuys is 35 cents, so she should buy the case instead of buying it at work.

D: The case of water is $13.49. Since the individual bottles are cheaper in the vending machine, Sarah should buy the bottles at work.

Answers

Answer: B

Step-by-step explanation:

$13.49 ÷ 48 = $0.28 per bottle in the case

Answer:

Step-by-step explanation:

Step 1:

Cost of 1 case of water with 48 bottles - $13.49

Step 2:

Calculate cost of 1 bottle of water - (Cost of 1 case)/(Number of bottles)

13.49/48 = $0.28

Answer: B

Two ways you can evaluate 15(90-3)

Answers

15 of 90 minis 3 15 times 90 minus 3

15(90-3)
first way
15 times 90 = 135
15 times 3 = 45
135 - 45 = 90
second way
90-3 = 87
15(87) = 1305
.................................
First way is more likely to be correct....

Find the GCF of the following monomials. -50m 4 n 7 and 40m 2 n 10

Answers

Answer:

$10m^2n^7$

Step-by-step explanation:

$-50m^4n^7 \ and \ 40m^2n^(10)$

WE need to find GCf for both monomials. GCF is the greatest common factor

$-50 ->-1 \cdot 5 \cdot 5 \cdot 2$

$40 ->2 \cdot 2 \cdot 5 \cdot 2$

GCF is 2 times 5 =10

GCF of exponent is the lowest exponent

GCF of m^4 and m^2 is m^2

GCF of n^7 and n^10 is n^7

$-50m^4n^7 \ and \ 40m^2n^(10)$

GCF is $10m^2n^7$
