The polynomial expression for the profit earned from producing and selling d dog leashes is 9.6d - 8000 - 0.00003d² and the profit from 28000 leashes is $237280
An equation is an expression that shows the relationship between two or more variables and numbers.
Profit = revenue - cost
Hence:
Profit = d(13 - 0.00003d) - (8000 + 3.4d) = 9.6d - 8000 - 0.00003d²
When d = 28000:
Profit = 9.6(28000) - 8000 - 0.00003(28000)² = $237280
The polynomial expression for the profit earned from producing and selling d dog leashes is 9.6d - 8000 - 0.00003d² and the profit from 28000 leashes is $237280
