A company has an inventory of books that is decreasing at a constant rate. After selling the book for 4 days, they have 8.840 bo

Answer:

The linear equation is:

$B(d) = 9500 - 165d$

Step-by-step explanation:

Linear function:

A linear function has the following format:

$y = mx + b$

In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).

A company has an inventory of books that is decreasing at a constant rate. Write a linear equation for B in terms of d.

This means that the situation is modeled by a linear function in the following format:

$B(d) = B(0) + md$

After selling the book for 4 days, they have 8.840 books in stock and after selling it for 10 days they have 7,850 books in stock.

This means that B(4) = 8840, B(10) = 7850

Finding the slope:

The slope, having two points, is given by the change in the output(in this case B) divided by the change in the input(in this case d).

We have the points

(4,8840) -> When d = 4, B = 8840

(10,7850) -> When d = 10, B = 7850

Change in B: 7850 - 8840 = -990

Change in d: 10 - 4 = 6

Slope: $m = \frac{-990}{6} = -165$

$B(d) = B(0) - 165d$

(10,7850) -> When d = 10, B = 7850

We use this to find B(0). So

$B(d) = B(0) - 165d$

$7850 = B(0) - 165*10$

$B(0) = 9500$

The linear equation is:

$B(d) = 9500 - 165d$

Eric wants to send a package to his mother. If he chooses UPS, the fixed express fee is 10 dollars and each kilogram costs 2 dol

o-na [289]

Answer:

10kg

Step-by-step explanation:

For UPS;

express fee = $10

If one kg costs $2, then x kg of package will coat $2x

Total cost of shipping xkg of package will be 10+2x

For FedEx;

Fixed express fee = $20

If one kg costs $1, then x kg of package will coat $1x

Total cost of shipping x kg of package is 20+x

If the total costs of the two options are the same, then;

10+2x = 20+x

2x-x = 20-10

x = 10.

Hence Eric sent 10kg of package
