Using proportions, it is found that:
A. The equation is 0.95x = 456.
B. The original price of the television was $480.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The television was sold with a 5% discount at $456, that is, 95% of the original price is of $456, hence:
0.95x = 456
x = 456/0.95
x = $480.
Thus:
A. The equation is 0.95x = 456.
B. The original price of the television was $480.
