$56.70 take away the tax first which brings you to $54 then 54x.10% is 5.40 so take 5.40 away from $54 you then have $48.60 then you can add the tax back in +2.70 = $51.30

What is a profit in business?

  • In its simplest form, it's the amount left after subtracting your total expenses from your total revenue.
  • The money remaining, your profits, can either be kept in the business and re-invested to finance future growth, or distributed as a draw or dividends to stakeholders.

The profit model, P(x) = -10x² + 498x - 1,500

Where, x = price per sign sold

If the price per sign sold is $20. Hence, x = $20

The profit made can be calculated thus :

Put x = 20 in the profit function :

P(20) = -10(20)² + 498(20) - 1,500

P(20) = - 10(400) + 9960 - 1500

P(20) = - 4000 + 9960 - 1500

P(20) = $4,460

The profit made is $4,460

How many years will it take for an initial investment of $20,000 to grow to $30,000? Assume a rate of interest of 6% compounded
Genrish500 [490]

F   =   Pe^(rt)

F is the final amount

P is the principal

r is the interest rate

t is the time in years

30000=20000 e^(.06t)

divide by 20000

3/2 = e ^ .06t

take the ln on each side

ln(3/2) = .06t

divide by .06

ln(3/2)/.06 =t

t=6.75775 years
