Answer:
$650. This was the original price.
Step-by-step explanation:
Let p represent the original price.
The following expression calculates the value of p: (1 - 0.38)p = $403. Note that '1' indicates full price and that '0.38' indicates a 38% discount.
(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.
Dividing both sides by 0.62 yields $650. This was the original price.

Variables - a quantity that may change, depends on the context of the math problem. Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc
