A Pairs socks that normally sells for eight dollars is on sale for 15% off find the sale price of the socks then find the total cost of the jeans if the sales tax rate is 8%

Answers

Answer:

Step-by-step explanation:

The original selling price of the pair of socks is $8. The pair of socks is on sale for 15%. The new selling price of the pair of socks would be the original price - 15% off the original price. It becomes

8 - (15/100 × 8) = 8 - 0.15×8 = 8 - 1.2 = $6.8

if the sales tax rate is 8%, it means that the total cost of the socks would be the new selling price + 8% of the new selling price. It becomes

Total cost of the pair of socks

= 6.8 + (8/100×6.8) = 6.8 + 0.08×6.8 = 6.8 + 0.544 = $7.344

Arithmetic series help!!!!

Answers

The initial term of the sequence is 15. The common difference is 3, so the n-th term (an) is

... an = 15 + 3(n-1)

For n=14, the 14th term of the sequence is

... a14 = 15 + 3(14 -1) = 54

The sum of terms is the average of the first and last, multiplied by the number of terms:

... sum = (15 + 54)/2·14 = 7·69 = 483

The appropriate answer choice is

... 54; 483

A jar contains 45 red candies and 60 black candies suppose a candy is selected at random what are the odds agianst selecting red candy

45 + 60= 105
then if you need to find the probability of the red candies you put
45/ 105

45+60=105
45/105= 8/21
