Question

the sales of lawn mowers t years after a particular model is introduced is given by the function y= 5500 in (9t+4) where y is the number of mowers sold how many mowers will be sold 3 years after a model is introduced

Answer 1

Given the sales of the mowers is modeled by y=5500ln(9t+4)
where t is the number in year, then the sales after t=3 will be:
f(3)=5500ln(9*3+4)
f(3)=5500 ln(31)
f(3)=$18,886.93
