Acompany estimates that the revenue (in dollars) from the sale of x doghouses is given by r(x) = 10,000 ln (0.01 x + 1). use the differential to approximate the change in revenue from the sale of one more doghouse if 120 doghouses have already been sold.

$45.45

Step-by-step explanation:

Data provided in the question:

Revenue function, R(x) = 10,000 ln(0.01 x + 1)

now,

change in revenue from sales doghouses i.e,

 =

because =  

at x = 120

 =

or

 =

or

 =

or

 = $45.45

hence,

the change in revenue from the sale of one more doghouse if 120 doghouses have already been sold is $45.45
