Find the markup and the selling price of the following item. Round answers to the nearest cent. A chemistry set costing $27.50, marked up 32% on cost.

Answers

Answer 1

Answer:

The relationship between markup and cost is given in the problem statement.

markup = 0.32 × cost = 0.32 × $27.50 = $8.80

Selling price is the sum of cost and markup.

selling price = cost + markup = $27.50 + 8.80 = $36.30

Answer 2

Answer:

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.

$x=27.50*(32)/(100)$

$x=27.50*.32$

$x=8.8$

Therefore, mark up price is $8.80.

Since we know that selling price of any item equals the sum of cost and mark-up price of the item.

Let us find selling price of our chemistry set.

$\text{Selling price of chemistry set}=27.50+8.8$

$\text{Selling price of chemistry set}=36.30$

Therefore, the selling price of the chemistry set is $ 36.30.

What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

a model car has a scale of 3 cm : 2 m.

The length of the actual hood of the car is 1 m.

Now,

Set up a proportion:

3cm/2m = x/1m

Cross-multiply:

2x=3

Divide by 2:

x=1.5 cm

Hence, 1.5 cm is the length of the model.
