The original expression is given by:

The correct way to rewrite the expression is given by:

For this, we use two properties:
Associative property:
The way of grouping the factors does not change the result of the multiplication:
Commutative property:
The order of the factors does not vary the product:
The linear equation of the tangent at point A is given by:

<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, to find the slope, we need to find the derivative at (4,3), using implicit differentiation. Hence:



Then:

We use point (4,3) to find b, hence:



Hence, the equation is:

If $1 is worth 30.23 rubles, just multiply 75 by 30.23
75*30.23=2,267.25
So, he'll get 2,267.25 rubles.
