An economist modeled the demand Q for a certain product as a linear function of the selling price p the demand was 20000 units when the selling price was $40 per unit and the demand was 15,000 units when the selling price was $60 per unit based on the model what is the time and in units when the selling price is $55 per unit

Answers

Answer 1

Answer: 16,250 units.

Step-by-step explanation:

This is a linear function which means that it takes the form of y = mx + c.

Y is the demand

X is the price

Find m.

= (Y₂ - Y₁) / (X₂ - X₁)

= (15,000 - 20,000) / (60 - 40)

= -250

Find c using substitution;

20,000 = -250 * 40 + c

20,000 = -10,000 + c

c = 20,000 + 10,000

c = 30,000

Linear function is;

y = -250x + 30,000

If selling price is $55;

y = -250 * 55 + 30,000

y = 16,250 units.

Answer 2

The demand is 17000 units when the selling price is $55 per unit

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let Q represent the demand and P represent the selling price.

20000 units for selling price of $40, hence (40, 20000). 16000 units for selling price of $60, hence (60, 16000).

Hence:

[tex]Q-Q_1=\frac{Q_2-Q_1}{P_2-P_1}(P-P_1)\\\\Q-20000=\frac{16000-20000}{60-40}(P-40)\\\\Q=-200P+28000[/tex]

For P = 55 unit:

W

Q = -200(55) + 28000 = 17000

The demand is 17000 units when the selling price is $55 per unit

Ezra has two weeks to sell popcorn to earn money for camp. For each unit of popcorn that he sells, Ezra will earn $5. He wants to earn at least $250
. During the first week he earned $105.
How many units of popcorn must Ezra sell in the second week to earn at least $250 in the two weeks combined?

Answers

okay so-
in the first week he sold 21 units of popcorn
he needs to sell 50 units in all
so 50-21= 29
he needs to sell 29 more units of popcorn

The number of units that needs to be sold to earn at least $250 is 20.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The minimum amount that needs to be earned = $250

One unit cost = $5

The amount earned in the first week = $105

Number of units = x

The number of units to sell in the second week.

150 + 5x ≥ 250

5x ≥ 250 -150

5x ≥ 100

x ≥ 20

Thus,

20 units need to be sold to earn at least $250.

Mr. Roy was creating bundles for his classes. He had 20 pencils, 80 pens and 55 markers.
He wanted each bundle to contain the same number of pencils, pens and markers.
a) What is the largest number of bundles he could create without any left over?

Answers

Answer:

The largest number of bundles he could create without any left over is 5.

Each bundle to contain 4 pencils, 16 pens and 11 markers

Step-by-step explanation:

Pencils = 20

Pens = 80

Markers = 55

a) What is the largest number of bundles he could create without any left over?

Find the highest common multiple of 20, 80 and 55

20 = 1, 2, 4, 5, 10, 20

80 = 1, 2, 4, 5, 8, 10, 16, 20......

55 = 1, 5, 11, 55

The highest common multiple of 20, 80 and 50 is 5

Pencils = 20 / 5

= 4

Pens = 80 / 5

= 16

Markers = 55 / 5

= 11

The largest number of bundles he could create without any left over is 5.

Each bundle to contain 4 pencils, 16 pens and 11 markers

Answers

Answer:

E: x = 13

F: x = 1.5 or 3/2

Step-by-step explanation:

This is for E:

x + 2/3 = 5

All you do is first multiply 5 * 3

and you will get 15

x + 2 = 15

Then you subtract from 15

15 - 2 = 13

So x = 13

This is for F:

10(x - 1) = 5

So all you do is distribute the 100 with x -1

10 * x = 100x

10 * -1 = 100

10x - 10 = 5

Then you add 10 to 15 because the number is -10

5 + 10 = 15

10x = 15

Now you divide by 10 on both sides

10x/10 = 15/10

10x/10 = x

15/10 = 3/2

So the answer for F is 3/2 or 1.5

If f(x)=3x^5+2x^4+5, then what is the remainder when f(x) is divided by x−1?

Answers

Answer:

The remainder is 10

Step-by-step explanation:

The find the remainder when f(x) divided by g(x), find the value of x when g(x) = 0, then substitute it in f to find the value of the remainder

∵ f(x) = 3[tex]x^{5}[/tex] + 2[tex]x^{4}[/tex] + 5

∵ f(x) is divided by x - 1

g(x) = x - 1

→ Equate g(x) by 0 to find x

∵ g(x) = 0

x - 1 = 0

→ Add 1 to both sides

∵ x - 1 + 1 = 0 + 1

x = 1

→ Substitute x in f by 1

∵ f(1) = 3[tex](1)^{5}[/tex] + 2[tex](1)^{4}[/tex] + 5

∴ f(1) = 3(1) + 2(1) + 5

∴ f(1) = 3 + 2 + 5

f(1) = 10

∵ The remainder is the value of f(1)

The remainder is 10
