1. There was a particular time that I wanted to buy a pen which costs $2 each. I wanted to buy 5 pens which would be $10. When I got to the stationary store, I was informed that the pen was now $2.50 each. Due to this, I could only buy 4 pen. This shows that due to an increase in price, the quantity demanded of pen that I could buy was reduced.
