Answer:
The original price per loaf is $250.
Explanation:
Theory. There are 2 ways of discounting a percentage from a number:
1. Calculate the 40% of the number (multiplying by 0.4) and substract the resulting amount from the original number,
2. Multiply the number by 1-40% (1-0.4).
1. Form an equation.
Using the logic expressed at the beginning of this answer, the resulting number of the price must have been multiplied by 1-0.4 to be the number that it is right now. Hence, this is the equation that represent the calculations made to obtain the discounted price:
, where x is the original price of the bread loaf.
2. Divide by (1 - 0.4) on both sides of the equation.

3. Calculate.

4. Express your result.
The original price per loaf is $250.
