The cost of a sleeping bag has been discounted by $22, so that the sale price of the bag is $52. Find the original price of the sleeping bag, p, by solving the equation p−22=52. The original price of the sleeping bag was $□.
Q. The cost of a sleeping bag has been discounted by $22, so that the sale price of the bag is $52. Find the original price of the sleeping bag, p, by solving the equation p−22=52. The original price of the sleeping bag was $□.
Understand the problem: Understand the problem.We are given the sale price of a sleeping bag, which is $52 after a discount of $22. We need to find the original price of the sleeping bag, which we will call p. The equation representing this situation is p−22=52.
Solve the equation: Solve the equation for p.To find the original price p, we need to add 22 to both sides of the equation to isolate p.p−22+22=52+22
Perform the addition: Perform the addition.Now, we add 22 to both sides of the equation.p=52+22p=74
Check the solution: Check the solution.We can check our solution by substituting p back into the original equation to see if it makes a true statement.74−22=5252=52This is a true statement, so our solution is correct.
