Kimmie sells custom T-shirts for $12 each at the flea market every Saturday She usually sells 36 T-shirts Kimmie surveys her customers about whether they would buy her T-shirts at a different price. She determines that for every $1 increase in price she would sell two fewer T-shirts and for even $1 decrease in price, she would sell two more T-shirts, Which quadratic function can Kimmie use to model price increments vs. total income so that she can find the price at which her income is maximized?

Answers

Answer:

y = -2*x² + 60*x

Step-by-step explanation:

The general form of a quadratic function is:

y = a*x² + b*x + c

We need to determine a ; b ; and c. For that we have three conditions therefore

Condition 1 at x = 12 $ each T-shirts kimmie sells 36 units, then she gets

12* 36 = 432 $ or y = 432 and

432 = a(12)² + 12*b + c or 432 = 144*a + 12*b + c

Second condition selling at 13 $ each T-shirt she sells 34 , then

13*34 = 442

442 = a(13)² + 13*b + c or 442 = 169*a + 13*b + c

And the third condition

11*38 = 418

418 = a* ( 121) + 11*b + c 418 = 121*a + 11*b + c

We have a three equation system

432 = 144*a + 12*b + c (1)

442 = 169*a + 13*b + c (2)

418 = 121*a + 11*b + c (3)

We need to solve it for a, b and c

Subtracting (2) - (1) 10 = 25*a + b and subtracting (2) - (3)

24 = 48*a + 2*b

Then b = 10 - 25*a and 24 = 48*a + 2*( 10 - 25*a )

24 = 48*a + 20 - 50*a

24 - 20 = -2*a

4 = - 2*a

a = - 2 and b = 10 - 25*( -2) b = 60

Finally c is: 432 = 144*a + 12*b + c

432 = 144* ( -2) + 12*60 + c

432 = - 288 + 720 + c

432 = 432 + c

c = 0

The quadratic function is:

y = -2*x² + 60*x

what is the remainder when 849,400 is divided by 216

Answers

The anserws is 88 so your welcome

Answer:

The remainder is 88

Step-by-step explanation:

The Remainder of a Division

We have to find the remainder when we divide 849,400 by 216.

It could be found by doing the long division, but we'll do it with a calculator.

Entering the division in the calculator we get:

849,400/216=3,932.4074...

We take the whole part of the quotient (3,932) and multiply it by the divisor:

3,932*216=849,312

The remainder is obtained by subtracting 849,400-849,312=88

The remainder is 88

s'ams mother is twice as old as sam in 12 years sam will be as old as his mother was 12 years ago how old are sam and his mother now? sam is?years old his mother is ? years old

Answers

Answer:

Sam is 24 years old and his mother is 48 years old.

Step-by-step explanation:

Equations

Let's call

x = Sam's current age

Since Sam's mother is twice as old as Sam:

2x = Sam's mother current age

x + 12 = Sam's age in 12 years

2x - 12 = Sam's mother age 12 years ago

These two last expressions are equal:

x + 12 = 2x - 12

Subtracting x and adding 12:

x = 24

2x = 48

Sam is 24 years old and his mother is 48 years old.

Answer:

Sam is 24 and his mom is 48

Convert the following recipe for 12 portions so that it yields 60 portions.
Stir Fried Chicken
3 lb chicken 6 oz. soy sauce 1 lb. green peppers
1/2 lb. scallions 2 oz ginger
2 cups Water

Answers

Answer:

15lb chicken 30 oz. soy sauce 5lb. green peppers

2 1/2 lb. scallions 10 oz. ginger

10 cups Water

To make 60 proportions of Stir Fried Chicken requires 15lbs of chicken,

30 oz of soy sauce, 3 lb. green peppers, 5/2 lb scallions, 10 oz ginger, and 10 cups Water.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given 12 portions of Stir-Fried Chicken requires 3 lb chicken 6 oz.

soy sauce 1 lb. green peppers

1/2 lb scallions

2 oz ginger

2 cups Water.

∴ To make 60 proportion or (12×5) proportion we have to multiply each ingredient by a factor of 5.

So, 60 proportions of Stir-Fried Chicken requires (3×5) = 15lbs of chicken,

(6×5) = 30 oz of soy sauce, (1×3) = 3 lb. green peppers, (1/2×5) = 5/2 lb scallions, (2×5) = 10 oz ginger and (2×5) = 10 cups Water.
