Among 143 subjects with positive test results, there are 24 false positive results; among 157 negative results, there are 3 false negative results. These results can be put in the following tabular form: Used Did not use Positive Test Result 119 24 Negative Test Result 3 154 If one of the test subjects is randomly selected, find the probability that the subject tested negative or used marijuana. Give answer as a decimal rounded to 2 decimal places.

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
