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.

Step-by-step explanation:
P = 300 + 60t
540 = 300 + 60t
540-300 = 60t
240 = 60t
240/60 = 4 (4 years after 2010)
So the year should be 2014
