In a particular county, a sample of the population showed that 84% of the households lived in
the same residence as they had the previous year. the estimate had a margin of error of 1.5% at
the 90% confidence level. if the county has 50,000 households, which of the following best
estimates the number of households that lived in the same residence as they had the previous
year, at the 90% confidence level?

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
