To find the percentage discount, we need to calculate the difference between the old price and the new price and then express it as a percentage of the old price.
The new price of the box is the old price plus the increment:
New Price = Old Price + Increment
New Price = 300 naira + 500 naira
New Price = 800 naira
The discount is the difference between the old price and the new price:
Discount = Old Price - New Price
Discount = 300 naira - 800 naira
Discount = -500 naira
To express this discount as a percentage of the old price:
Percentage Discount = (Discount/Old Price) * 100
Percentage Discount = (-500 naira / 300 naira) * 100
Percentage Discount = -166.67%
Note: The percentage discount is negative because the new price is higher than the old price.
The old price of a box is 300 naira if there is an increment of 500 naira find the percentage discount
