A company owns two manufacturing
SVETLANKA909090 [29]

Answer:

3x+24 more widgets

Step-by-step explanation:

A company owns two manufacturing plants:

  • 1st plant: 8x+17 widgets;
  • 2nd plant: 5x-7 widgets.

To find how many more items the first plant produces daily than the second plant, we have to subtract from the number of widgets the first plant produces the second plant produces. So,

(8x+17)-(5x-7)\\ \\=8x+17-5x+7\ [\text{Eliminate brackets}]\\ \\=(8x-5x)+(17+7)\ [\text{Combine the like terms}]\\ \\=3x+24

A charter fishing company buys a new boat for $224,000 and assumes that it will have a trade-in value of $115,200 after 16 years
vodka [1.7K]

First, according to the information, we build a linear model, and then, the model is used to find the information asked.

a) The linear model is:

V(t) = 224000 - 6800t

b) The depreciated value of the boat after 10 years is of $156,000.

c) The depreciated value falls below $100,000 after 18.24 years.

d) The sketch is given at the end of the answer.

Item a:

  • The initial value is of $224,000, thus, the y-intercept of the linear function is of b = 224000.
  • The value decayed to $115,200 in 16 years, thus, the slope of the linear function is:

m = \frac{115200 - 224000}{16} = -6800

Then, the linear model is:

V(t) = 224000 - 6800t

Item b:

The value after 10 years is V(10), so:

V(10) = 224000 - 6800(10) = 156000

Then, the depreciated value of the boat after 10 years is of $156,000.

Item c:

This is t for which: V(t) = 100000. So

V(t) = 224000 - 6800t

100000 = 224000 - 6800t

6800t = 224000 - 100000

6800t = 124000

t = \frac{124000}{6800}

t = 18.24

The depreciated value falls below $100,000 after 18.24 years.

Item d:

The sketch is appended at the end of this answer.
