klasskru [66]

The number of years it would take sales to reach $1,750,000 is 14.65 years.

<h3>What is the number of years?</h3>

The formula that can be used to determine the number of years it would take for the sales to reach $1,750,000 is:

Number of years : In (FV / PV) / r

Where:

  • FV = future level of sales -  $1,750,000
  • PV = present level of sales = 850,000
  • r = rate of growth -  4.931998%

Number of years : In ($1,750,000 / 850,000) / 0.04931998

Number of years : In (2.06) / 0.04931998

Number of years : 14.65 years
