A company's daily profit from the production and sale of electrical components can be described by the equation $P(x)=6.40x-2.435$ dollars, where $x$ is the number of units produced and sold. What level of production and sales will give a dally profit of more than $\mathrm{\$}7,805$ ?
The company must manufacture and sell more than units

Step 1 ：The company's daily profit from the production and sale of electrical components can be described by the equation $P(x)=6.40x-2.435$ dollars, where $x$ is the number of units produced and sold. We need to find the level of production and sales that will give a daily profit of more than $7805.

Step 2 ：We can do this by setting up the inequality $6.40x-2.435>7805$ and solving for $x$.

Step 3 ：The solution to the inequality is $x>1219.91171875000$. However, since the number of units produced and sold cannot be a fraction, we need to round this number up to the nearest whole number.

Step 4 ：So, the company must manufacture and sell more than $\boxed{{\displaystyle 1220}}$ units to achieve a daily profit of more than $7805.
