Help i dont understand this.

Answer 1

Answer: 1 * 1 = 1
11 * 11 = 121
111 * 111 = 12321
1111 * 1111 = 1234321
11111 * 11111 = 123454321
111111 * 111111 = 12345654321

the pattern is that with each '1' added, there is another consecutive number added. if there are 3 ones, it I'll go up to 3 and then back down to 1 (111*111=12321)
it is the same like that for every one.

Compute the sales tax on the following transactions. An article retails for $38.50. The city sales tax is 4%, and the federal excise tax is 7%. How much is the total tax? A. 1.54 B. 2.70
C. 4.24
D. 34.26

Answers

The answer is C) 4.24

4% + 7% = 11%

to get 11% of 38.50 you move the decimal two spaces to the left on the percent and multiply that number by the other number.

11% ---> .11

38.50 x .11= 4.24.

I hope this answer gave you a better understanding on how to work with percentages! :) Have a good day :)
