When a price is increased by x percent, we multiply the price by
.
In this case, the price is $1260 and it increases by 50%. When we put that in an equation:
So, the increased price is $1890.
After that, they applied a discount of 50% to the increased price. To find a decreased price we multiply the price by:
.
So, after the discount the final price becomes
.

20 - 5(4)
20 - 20
= 0
