Answer:
112 $ is the original price
Step-by-step explanation:
[tex]x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112[/tex]
you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale
