The sales of lawn mowers t years after a particular model is introduced is given by the function y = 5500 ln(9t + 4), where y is the number of mowers sold. how many mowers will be sold 5 years after a model is introduced? round the answer to the nearest whole number.

21450 mowers have been sold in 5 years.

Step-by-step explanation:

The function for the sales of lawn mowers t years is given by

y = 5500 ln(9t + 4)

where t is in years and y represents number of mowers.

We have to calculate the sales of mowers after 5 years.

So we will use the function to calculate the numbers by putting t = 5

y = 5500×ln(9×5 + 4) = 5500×ln(45+4) = 5500×ln(49) = 5500×ln(7²)

y = 5500×[2ln(7)] = 5500×2×(1.95) = 21450

Therefore answer is 21450 mowers have been sold

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
