Cost- 50 Selling Price- 125

Mark up rate - Unknown, Operating Profit- unknown Exected monthly sales (unit) 100

Need to solve for Mark up rate & Operating profit

Factor the polynomial x2 + 3x – 18. Which one of the following is a factor?

Factor the polynomial 12x2 + 11x – 5 completely.

Factor the polynomial 18a2b – 4ab + 10a completely

Factor the polynomial 2x2 – 50 completely.

Ahhh..... im lost.... we use forumlas such as SP= C(1-d).. I need it put in that kind of perspective

To solve for the markup rate and operating profit, we can use the following formula:

Selling Price = Cost + (Cost x Markup Rate)
Operating Profit = (Selling Price - Cost) x Quantity Sold

Given:
Cost = 50
Selling Price = 125
Quantity Sold = 100

Step 1: Solve for Markup Rate
125 = 50 + (50 x Markup Rate)

To isolate the markup rate, we can subtract 50 from both sides:
125 - 50 = 50 + (50 x Markup Rate) - 50
75 = 50 x Markup Rate

Divide both sides by 50:
Markup Rate = 75 / 50
Markup Rate = 1.5 or 150%

Therefore, the markup rate is 150%.

Step 2: Solve for Operating Profit

Operating Profit = (Selling Price - Cost) x Quantity Sold
Operating Profit = (125 - 50) x 100
Operating Profit = 75 x 100
Operating Profit = 7500

Therefore, the operating profit is 7500.

To summarize:
Markup Rate = 150%
Operating Profit = $7500
