You need to choose price in such a way that mxm customers are able to buy your phone
If u choose price as 20
then, customers with budget(53,30,20) can afford it and your profit will be 60.
let us assume i set the price 20.
then only the customer with price 20 will be able to buy it.
No. Any customer having budget more than or equal to 20 can buy it.
Only the customer with budget less than 20 can’t buy it.
