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 4.5 years after a model is introduced?

Respuesta :

Answer:

20875

Step-by-step explanation:

Given:

y = 5500 ln (9t + 4

y is number of mowers sold

t is years after a particular model is introduced

f(t)= 9t+4

How many mowers will be sold 4.5 years after a model is introduced?

t=4.5

putting t=4.5 in given function we get,

y= 5500ln(9(4.5) +4)

       = 20875.19

20875 mowers will be sold 4.5 years after a model is introduced!
