Answer:
The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price. The original price was $375.36
Step-by-step explanation:
Lets work it out and compare our work. Since its 31% off, the formula we need to use is original times percent off equals the new price. Let x equal the original.
x*.69=259
Divide both sides by .69
(x*.69)/.69=259/.69
Divide
x=375.36
The original price was $375.36
The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price.
