3. A retailer sales one gold watch with a markup of 50%. Write an equation using (C) retail cost of watch and (s) for sale price, If the retailer sold the watch for $300, what was the cost to the retailer?​

Respuesta :

Answer:

a. S = 1.5C

b. C = $200

Step-by-step explanation:

Firstly, we want to write an equation using retail cost of watch and s for sale price

From the question, we are looking at a markup of 50%

Mathematically therefore;

S = C + (50/100 * c)

S = C + 0.5C

S = 1.5C

Now we want to calculate the cost to the retailer given that the watch was sold as $300 by the retailer

We use the equation:

S = 1.5C

300 = 1.5C

C = 300/1.5

C = $200
