An album which originally cost p 900, mark up with 30%. What is the selling price? A. p 970.00 B. p 1070.00 C. p 1170.00 D.p 127
egoroff_w [7]

The markup percentage specifies the amount by which the selling price is

raised above the cost price.

  • The correct option for the selling price is <u>B. p 1,070.00</u>

Reasons:

The original cost of the album = p900

The mark up percentage = 30%

Required:

The selling price

Solution:

The percentage mark up is given by the difference between the price at

which an item is for sale and its cost expressed as a percentage.

\displaystyle Percentage \ mark \ up = \mathbf{\frac{Selling \ price - Cost \ price}{Cost \ price} \times 100}

Therefore, we have;

\displaystyle 30 = \frac{Selling \ price - 900 }{900}  \times 100

\displaystyle 0.3 = \frac{Selling \ price - 900 }{900}

900 × 0.3 = Selling price - 900

270 = Selling price - 900

Selling price = 900 + 270 = 1,070

The selling price is <u>B. p 1,070.00</u>

Zion and Lily are reading the same copy of the same book for a summer reading
Mars2501 [29]
Here’s how you can set up the problem:
10 + 25d = 40 + 10d
(d means pages per days)
15d = 30
D = 2

So, the answer would be two days. You can check this by plugging it into the problem:
10 + 25(2) = 40 + 10(2)
10 + 50 = 40 + 20
60 = 60; correct!

Hope this helped! :)
