a new trendy restaurant is growing exponentially. after being open for 11 months the restaurant was serving an average of 310 customers a day. by month 15, the restaurant was serving about 456 customers a day. write an exponential function n(t) that models average number of customers, n, after t months of being open. if necessary, round any values to four decimal places (do not round on intermediate steps). write your answer in the form a(b)t

the exponential function is n(t) =n° (1+r)∧t, where t is the power refers the time in months after opening and n denotes average customer.

when the rate of increases is occurred very rapidly. In this question, the trendy restaurant has earned reputation.

Given, average number of customers after 11 months of opening = n(11) =310

average number of customers after 15 months of opening= n(15) =456

during this 4 month increases of customer =456 -310 =146

increasing rate of customer per month = 146/4 = 36.5

now increasing rate in percentages = 36.5 %

exponential growth rate, r= 0.365

let, n° is the initial number of customer while opening at t=0 month

now, the exponential function n(t) that model's average number of customers, n after t months of being open will be

n(t) = n° ( 1+r)∧t

we are given that after 11 months of opening average customer n(11) = 310

now, 310 = n° (1+ 0.365)∧11

n° = 10

hence, the exponential function = n(t) = 10(1+r)∧t
