Answer: $72
Step-by-step explanation: You have to realize that $54 is 75% of the original price, meaning that $54 is 3/4 of the original. Therefore, you must divide 54 by 3 to get 18, which is 25% of the origianl price. Since you now know what 25% of the original price is, you just have to add 18 to 54 to get $72. 72 dollars is 100% of the original price of the coffee table.
