The revenue from manufacturing and selling x units of toaster ovens is given by:
nexus9112 [7]

Answer:

$248,000.

Step-by-step explanation:

We have been given that the revenue from manufacturing and selling x units of toaster ovens is given by R(x)=-0.3x^2+200x-82,000.

To find the amount of revenue earned from selling 3,000 toaster, we will substitute x=3,000 in the given formula as:

R(3,000)=-0.03(3,000)^2+200(3,000)-82,000

R(3,000)=-0.03*9,000000+600,000-82,000

R(3,000)=-270,000+518,000

R(3,000)=248,000

Therefore, the company should expect revenue of $248,000 from selling 3,000 toaster ovens.

Paga No. Date: 6. When a discount of 25% is allowed on the marked price then the selling price will be 1425 .lf the marked price
SVETLANKA909090 [29]

Answer:

The percentage loss = 10.9375 %

Step-by-step explanation:

Let the cost price = x

Since the marked price is 18.75% above the cost price so the

Marked price = 1.1875 x

When a discount of 25% is allowed on the marked price , the selling price will be Rs. 1425

⇒ Marked price × 0.75 = 1425

⇒ Cost price × ( 1.1875 × 0.75 ) = 1425

⇒ Cost price × ( 0.890625 ) = 1425

⇒ Cost price = 1600

Selling price = 1425

So percentage loss =  × 100

% Loss =  × 100

% Loss = 10.9375 %
