Answer:
Step-by-step explanation:
The cost of a sleeping bag has been discovered to be $21
The sale price of the bag is $53
The original price of the bag, P is represented by the equation,
P-21 = 53
To find the original price of the sleeping bag P, we would solve the equation, P - 21= 53
P - 21= 53
We will ad 21 to the left hand side and right hand side of the equation. It becomes
P - 21 + 21 = 53 + 21
P = $74
