CP=500

SP=550

<h3><u>To</u><u> </u><u>find</u><u>:</u><u>-</u></h3>

Profit and profit%

<h3><u>Solu</u><u>tion</u><u>:</u><u>-</u></h3>
  • CP =500
  • SP=550

We know that

\boxed{\sf Profit=SP-CP}

\\ \tt{:}\leadsto Profit=550-500

\\ \tt{:}\leadsto Profit=Rs.50

<h3>And</h3>

\boxed{\sf Profit\%=\dfrac{Profit}{CP}\times 100}

\\ \tt{:}\leadsto Profit\%=\dfrac{50}{500}\times{100}

\\ \tt{:}\leadsto Profit\%=\dfrac{50}{5}

\\ \tt{:}\leadsto Profit\%=10\%

klio [65]

Answer:

  1. The first mistake was in not taking 18% off the iPad price. A second mistake was in using an incorrect value for the sales tax multiplier. Those two mistakes together are why the answer is incorrect.
  2. ($575 +0.82·2·499)·1.08875 = $1517.02

Step-by-step explanation:

iPads are 18% off on the day of purchase, so they should be charged at ...

   100% -18% = 82%

of full price. The sum shown includes two iPads at $499 each, without any discount. The total price is too high by $179.64.

The tax rate is given as 8.875%, so the multiplier on price will be ...

  100% +8.875% = 108.875% = 1.08875

The multiplier used by the student in the problem is 1.0875, so is too low.

_____

A correct computation could be written as ...

  ($575 + 2×499×0.82)×1.08875 ≈ $1517.02

matrenka [14]

Answer:

3.803% Profit

Step-by-step explanation:

First let us calculate total sales, then calculate the total cost, and then divide the two.

Sale: 120*1.1=132 and 52*.9=46.8

Cost: 120 and 52

Profit equation:

\frac{Net sales-COGS}{Net Sales} =Profit

\frac{(132+46.8)-(120+52)}{(132+46.8)}

Simplify:

\frac{6.8}{178.8} =.03803 or 3.803% Profit

Answer:

Interest rate, R = 244%

Step-by-step explanation:

Given the following data;

Principal = $270

Simple interest = future amount - principal = 309.60 - 270 = $39.60

Time = 22/360 = 0.06 years

To find the interest rate?

Mathematically, simple interest is calculated using this formula;

S.I = \frac {PRT}{100}

Where;

  • S.I is simple interest.
  • P is the principal.
  • R is the interest rate.
  • T is the time.

Substituting into the equation, we have;

39.60 = \frac {270*R*0.06}{100}

Cross-multiplying, we have;

39.6 * 100 = 16.2*R

3960 = 16.2R

R = \frac {3960}{16.2}

<em>Interest rate, R = 244.44 ≈ 244%</em>

<em>Therefore, the pawnbroker charged Elisa a simple interest rate of 244%.</em>
