A store sells gas and containers. One customer buys 2 containers and 8 gallons of gas for $38.06. Another customer

buys 1 container and 3 gallons of gas for $15.76.

Enter the price ,in dollars, of 1 container

Answers

Answer:

$5.95

Step-by-step explanation:

Given :

Let containers = c ;Gallon of gas = g

2c + 8g = 38.06 - - - (1)

c + 3g = 15.76 - - - - (2)

From (2) :

c = 15.76 - 3g

2(15.76 - 3g) + 8g = 38.06

31.52 - 6g + 8g = 38.06

2g = 6.54

g = 6.54 / 2

g = 3.27

Recall :

c = 15.76 - 3g

c = 15.76 - 3(3.27)

c = 5.95

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.


y = -x^2 + 99x - 932

Answers

Answer:

$49.5

Step-by-step explanation:

y = -x^2 + 99x - 932

The maximum point is :

dy/dx = 0

Take the first derivative of y

dy/dx = - 2x + 99

Put - 2x + 99 = 0

-2x = - 99

x = 99 / 2

x = 49.5

Hence, To make maximum profit, widget should be sold at $49.5 per widget.

The ages of George and Genemy are in ratio 5:7 . Four years from now the ratio of their ages will be 3:4 .Find their present ages.​

Answers

Answer:

Below in bold.

Step-by-step explanation:

Let x be George's age and y be Genemy's age.

x/y = 5/7

(x + 4)/ (y + 4) = 3/4

From equation 1, y = 7x/5 = 1.4x so substituting in equation 2 :

(x + 4)/ (1.4x + 4) = 3/4

3(1.4x + 4) = 4(x + 4)

4.2x + 12 = 4x + 16

0.2x = 16 -12 = 4

x = 4/0.2 = 20 = George's age.

So y = 1.4x = 1.4 * 20 = 28 = Genemy's age.
