PLS HELP ME ON MY DIAGNOSTIC!!!

Let the original price = x
He paid 70% of the original price so 0.70x
This equaled $14:
SO the equation is 0.70x = 14
Solve for x by dividing both sides by 0.70:
x = 14/0.70
x = 20
The original price was $20
Answer:
Let the original price be x.
Joe paid $14.00 for a board game which is the 70% of the original price.
Therefore, the original price is
[tex]70\% \: of \: x = 14 \\ \frac{70}{100}x = 14 \\ x = \frac{14 \times 100}{70} \\ \boxed{ x = 20}[/tex]
