Question

The formula = () − applies to the demand of a product, where q is the number of units and P is the price of one unit. How many units will be demanded if the price is Rs. 18.00?

Answer 1

4320 units quantities were demanded

Explanation:

Given:

`p = 90 (5) - (q)/(10)`

Required:

The units demanded when price = 18.00

This implies that:

`p = 18.00`

So, we have:

`p = 90 (5) - (q)/(10)`

`18.00 = 90(5) - (q)/(10)`

Open bracket

`18.00 = 450 - (q)/(10)`

Collect like terms

`(q)/(10) = 450 - 18.00`

`(q)/(10) = 432`

Solve for q

`q = 432 *10`

`q = 4320`
