What is the common ratio of the following sequence? -1, 6, - 36, 216 . . .

r = -6

r = 1296

r = -1

r = 7

r = -6

Step-by-step explanation:

-1 × -6 = 6

6 × -6 = -36

-36 × -6 = 216

-6

Step-by-step explanation:

To find the common ratio, take the second term and divide by the first term

6/ -1 = -6

Check the third term and divide by the second term

-36/-6 = -6

And the 4th divided by the third

216/ -36 = -6

The common ratio is -6

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
