25,000 - 8,500 = 16,500
16,500 :1250 = 13 years and 2 months
Sorry for the delay!
Let x = charge before tax in 1st city, and y = charge before tax in 2nd city
y = $1500 + x
4/100x => tax in first city
3.5/100y => tax in second city
0.04x + 0.035y = $408.75
We have the following system of equations to solve:

So the hotel charge before tax in city 1 = $4750, and the hotel charge before tax in city 2 = $6250
Answer: -3 x 3= -9 x -1= 9
Step-by-step explanation: So, you need to times -3 with 3 and you should get -9 then, times -9 with -1 and you get 9.
Answer:
The upper limit of the 95% confidence interval is:
C.I_u = 200 + (58.8/
)
Step-by-step explanation:
The formula is given as:
C.I = μ ± Z*σ/
The upper limit => C.I_u = μ + Z*σ/
The lower limit => C.I_l = μ - Z*σ/
The sample size (n) is not stated in the question. Hence, we calculate the upper limit with respect to n.
The upper limit => C.I_u = 200 + 1.96*(30/
)
= 200 + (1.96*30)/
= 200 + 58.8/
