Step-by-step explanation:
Simplify each equation using PEMDAS:
Parentheses (x)
Exponents x²
Multiplication and Division, left to right × ÷
Addition and Subtraction, left to right - +
It is also important to follow PEMDAS when working within grouping symbols like parentheses.
Also, remember that two negatives make a positive, and when a negative and positive are multiplied, the result is always negative.

Ok, this is how I tackle these problems - 1) I evaluate what's happening in the problem. Chairs are being sold at a store on sale. 2) I write the problem out in stages as shown:
36 x .60 = 21.60 Calculate the markup of 60 percent.
36.00 + 21.60= 57.60 Add the markup to the original price.
57.60 x .20 = 11.52 Find the discount of 20 percent on the new price.
57.60 - 11.52 = 46.08 Subtract the discount from the new price.
46.08 x 2 = $92.16 Multiply the discounted price by 2 to find the price of 2 chairs.
