According to the mathematical expression given, the height of the tree after 6 years will be 44 inches.

<h3>How is the value of an expression calculated?</h3>

For a mathematical expression containing one or more variables, the value of the expression can be calculated by substituting a particular value of the variables. For example, consider the expression 2x+3y. For x=2 and y=3, the value of this expression will be   2x+3y=2\times 2+3\times 3=4+9=13.

Here, in this question, the height of a tree is approximated by the expression 4t+20, where t is the number of years.

Now, we are to calculate the height of the tree after 6 years. For this, we have to substitute t=6 in the given expression.

Hence, the height of the tree will be: H=4\times 6+20=44\hspace{1mm} \text{inches}.

Therefore, according to the mathematical expression given, the height of the tree after 6 years will be 44 inches.

<u>The </u><u>profit </u><u>made is </u><u>$4,460.</u>

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
