After allowing 20% discount on the marked price with 13%

saveliy_v [14]

Answer:

The marked price of the article is 22,600

Explanation: 

Given, selling price of an article SP = Rs. 18080

To calculate marked price MP, the formula used is

$\mathrm{SP}=\mathrm{MP}\left(1-\frac{D \%}{100}\right)$

Discount D = 20%

Substituting the given values

SP = $\mathrm{MP}\left(1-\frac{20}{100}\right)$

18080 = $\mathrm{MP}\left(1-\frac{1}{5}\right)$

$18080=\mathrm{MP}\left(\frac{4}{5}\right)$

$\mathrm{MP}=\frac{18080 \times 5}{4}$

MP = Rs. 22,600

Therefore the marked price of the article is 22,600

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.

Lady_Fox [76]

Answer:

$m(c(a)) = 4.8875a$

Step-by-step explanation:

The missing parameters are:

$c(a) = 4.25a$ --- Cost of marble countertops

$m(c) = 1.15c$ --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

$c(a) = 4.25a$

$m(c) = 1.15c$

$m(c) = 1.15c$ can be written as:

$m(c(a)) = 1.15*c(a)$

Substitute: $c(a) = 4.25a$

$m(c(a)) = 1.15*4.25a$

$m(c(a)) = 4.8875a$

Hence, the cost of marked up price is: $m(c(a)) = 4.8875a$
