You have $50 and want to buy some CD's. If prices of CD's rose from $5 each to $10, how would your quantity of demanded of CD's change?

Respuesta :

if you have 50$ and each cd = 5$
you would have 50÷5=10 CDs
but if you have 50$ and each CD=10$
you would have 5 CDs
so the change of the quantity is 5 CDs
