Suppose consumers will demand 40 units of a product when the price is $12 per unit and 25 units when the price is $18 each. find the demand equation assuming that it is linear. find the price per unit when 30 units are demanded.

The price per unit is $48, when 30 units are demanded.

Step-by-step explanation:

Since we have given that

At price of $12 per unit, the number of units demanded = 40 units

At price of $18 per unit, the number of units demanded = 25 units.

So, the coordinates would be

(40,12) and (25,18)

As we know that x- axis denoted the quantity demanded.

y-axis denoted the price per unit.

So, the slope would be

So, the equation would be

So, if 30 units are demanded, the price per unit would be

Hence, the price per unit is $48, when 30 units are demanded.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
