Answer: The change in revenue for the sale of 1 more doghouse $ 66.67 dollars
Explanation: Differential is a function that can be used to approximate function value with a great degree of accuracy. This is done by the following.
Mathematical definition of derivative: f'(x) = lim f(x+Δx) - f(x)/Δx.
If Δx is very small:
f'(x) . Δx ≅ f(x+Δx) - f(x)
Knowing that Δy ≅ f(x+Δx) - f(x) and the diferential of variable x can be written by dx as the variable y can be dy:
dy = f'(x) dx
which means that the differential dy is approximately equal to the change Δy, if Δx is very small.
For the question, R(x) = y(x) = 14,000ln(0.01x+1)
f'(x) =
Using the chain rule, the derivative will be:
f'(x) = 14,000.
dy = 14,000..dx
dx is the change in x. For the question, the change is 1 (1 more doghouse) and x is 110:
dy = 14,000
dy =
dy = 66.67
The change in revenue is $66.67 dollars.

Answer:
The question is missing some figures which can be seen from the attached image.
Petty cash is a fund set aside in the office to pay minor day to day expenses incurred.Usually, an amount is made available at the beginning of period called float,from which expenses can be paid and the amount equal to spend is reimbursed at the end of the month.
In order, to make payment even more easier,some businesses take up credit cards from financial institutions,from which expenses can be paid on account.
The balance of $415 means in petty fund,implies that $85 spent needs to be replenished at month end and that the remaining expenses were paid with credit card.
Explanation:
Find in the attached spreadsheet the entries posted in respect of petty cash and credit card expenses in the month.
