How to determine the original price of the kitchen table
Mr & Mrs Brown kitchen table was bought for $450
This amount is 75% of the original price = 0.75
Let's denote the original price of the kitchen table as P
So, 0.75 * P = 450
divides through by 0.75
P = 450/0.75
P = 600
Therefore, the original price of the kitchen table was $600
