Calls arrive at lynn ann fish's hotel switchboard at a rate of 2.0 per minute. the average time to handle each is 20 seconds. there is only one switchboard operator at the current time. the poisson and negative exponential distributions appear to be relevant in this situation. a) the probability that the operator is busy = nothing (round your response to two decimal places). b) the average time that a caller must wait before reaching the operator = nothing minutes (round your response to two decimal places). c) the average number of calls waiting to be answered = nothing calls (round your response to two 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
