Answer:

$262.65

Step-by-step explanation:

If each window costs 87.55, multiply 87.55 by 3. (87.55 x 3)

87.55 x 3 = 262.65

To check the answer: 262.65 divided by 3. This equals 87.55 so the answer is correct.

A recipe for beef stew calls for 1 pound of beef and 3 potatoes. The recipe is doubled to include 2 pounds of beef and 6 potatoe
vaieri [72.5K]

To answer the question, let B call the amount of meat and P the number of potatoes.

The recipe says that for every pound of meat we need 3 potatoes.

Then that relationship is written as follows:

1B = 3P

\frac{1}{3}=\frac{P}{B}

If we increase the amounts of the recipe by 100%, it will multiply by 2 the amount of meat and also that of potatoes. Therefore we need 2 pounds of meat and 6 potatoes.

Then the relationship is:

2B = 6P

\frac{2}{6}=\frac{P}{B}

But \frac{2}{6}=\frac{1}{3}

Therefore, the proportion that represents the situation remains the same 1B = 3P

This occurs because the increase in the amount of potatoes and beef was in the same proportion.

The sales at a particular bookstore grew from $2006 million in 2000 to $3803 million in 2005. Find an exponential function to mo
Mariana [72]
Yes initial amount is 2044 (in millions) 

Since the function is from 2000 then you can set it up as 
B(t)=2044*a^t 

To solve for "a" use the second number given, 3846, and since this value is 5 years after 2000 t=5 
so we plug in these values 
3846=2044*a^5 

we now solve for a 

first, divide by 2044 
3846/2044=a^5 

next, we take the 5th root 
<span>5sqrt(3846/2044) = a 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
