Expert Solution
Step 1

The demand for Bagels is as given :

Q=-20P+10Ps-20Pc+10I

P : Price of Bagels

Ps : Price of scones

Pc : Price of coffee

I : Income

 

The estimated demand function shows that :

1) A unit increase in the price of bagels will decrease the demand of Bagels by 20 units.

2) A unit increase in the price of scones will increase the price of Bagels by 10 units.

3) A unit increase in the price of coffee will decrease the price of Bagels by 20 units.

4) A unit increase in income of the consumer will increase the demand of Bagels by 10 units.
