It's the last lesson and I have a gap so I run at the coach's class. I knock on the door and as I entered he sighs. I see Harlan, Eli, Liam and Mason.

"May I talk to you for a second, coach?" he walks near me. "Could I retake it now? I have a gap. I'll sit at the back of the class and write it" he looks at the class.

"Come inside".

He hands me the test and I to at the back or the class. Harlan and Liam are sitting right in front of me. I take a photo of the test without the coach understands it and I send it to Stiles.

- Please help me or I won't play tonight.

1) When the price of a good is €2, 100,000 kilos of this good are demanded per day. When the price increases to €3, the quantity demanded changes by 20,000 kg.
• To find the arcuate elasticity of the good.
(SOLVED)

2) When the price of a product is €8, the quantity demanded is 160, and the elasticity of demand is -0.5. What will be the quantity demanded when a) the price increases to €10 and b) the price increases by €10?
(SOLVED)

3) Suppose that the demand curve of a good results from the relationship Qd1= 30-5P (where Qd is the demanded quantity and P is the price). If, after an increase in income, the demand curve results from the relationship Qd2=40-5P and at the same time there is an increase in the price from €4 to €6, find whether the quantity demanded increased or decreased. Also make a graph of the changes.
(SOLVED)

Stiles solved all of the problems on the test and I hope it's correct. The bell rings just in time that I'm done writing. Everybody packs and leaves. I pack and hand at coach my test.
