Answer:

1 3/4

Step-by-step explanation:

you have to convert the mixed numbers into improper fractions first

2 1/2 turns into 5/2

then you make the denominators the same

5/2 turn into 10/4

then you subtract

10/4 - 3/4 = 7/4

then you turn it into a mixed number

7/4 turns into 1 3/4

The demand function Q and cost function C(Q) of a commodity are given by the equations \[ Q = 20 - 0{,}01P\]

BartSMP [9]

The total revenue of the function is the product of the quantity and the price

The total revenue in terms of P is TR = 20P - 0.01P^2

<h3>How to determine the total revenue?</h3>

The demand and the cost functions are given as:

Quantity function, Q = 20 - 0.01P

Cost function, C(Q)=60+6Q

The total revenue is calculated as:

TR = Q * P

Substitute Q = 20 - 0.01P in the above equation

TR = P * [20 - 0.01P]

Evaluate the product

TR = 20P - 0.01P^2

Hence, the total revenue in terms of P is TR = 20P - 0.01P^2
