Sunrise, a bed-and-breakfast hotel, charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night. Craig wants to book a hotel for 5 nights.

Answers

Answer:

Sunrise $450 Bright Eyes $475

Step-by-step explanation:

Let x= number of days

Sunrise:

(25 + 85x)= total cost

(25+85(5))= $450

Bright Eyes:

(95x)= total cost

(95(5))= $475

The Bright eyes hotel would be more cost efficient than the Sunrise hotel.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Sunrise, a bed-and-breakfast hotel, that charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night.

The total cost for 5 nights at Sunrise hotel would be -

C(s) = 25 + 85 x 5 = $450

The total cost for 5 nights at Bright eyes hotel would be -

C(b) = 95 x 5 = $475

Therefore, the Bright eyes hotel would be more cost efficient than the Sunrise hotel.

Answers

Answer:

two unequal, complex roots

Step-by-step explanation:

Rewrite this quadratic as a^2 + 3a - 7 = 0.  The coefficients are {1, 3, -7}.  The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.

Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.

How would 125% be expressed as a decimal. You also need to explain what is the rule in changing Percent to decimal . Give another 3 examples . pa help po ty po in advance ❤

Answers

Answer:

Step-by-step explanation:

125 % can be expressed as decimal as

[tex]\frac{125}{100} \\\frac{25}{20} \\\frac{5}{4}[/tex]

Rule in changing Percent to decimal

a) Divide a percent by 100

b) Remove percent sign

example

30%

Diego has a water bottle and pours 6.8 ounces of water out from the full bottle. He estimates that he poured out 20% of the water in the bottle

Answers

Answer:

34 ounces

Step-by-step explanation:

Here is the full question

Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle?

Let b = total ounces in the bottle

the equation that can be derived from this question is :

0.2 x b = 6.8

To find b, divide both sides by 0.2

b = 6.8 / 0.2 = 34 ounces

Which linear function has the greatest initial value? Which has the greatest rate of change? Use the drop-down menus to show your answer


Function A: (0,0) (2,5) (4,10) (6,15)

Function B: Y = 3x-1

Function C: picture***​

Answers

Answer:

Step-by-step explanation:

The function C has the greatest initial value, and the function B has the greatest rate of change

Linear function

A linear function is a function whose value changes at a constant rate.

A linear function is represented as:

[tex]y = mx + c[/tex]

Where

m represents the ratec represents the initial value, or the value of the function, when x = 0

Initial values

The initial value of function A is 0.

This is so because y = 0, when x = 0

The initial value of function B is -1

This is so because the value of function y = 3x - 1 is -1, when x = 0

From the graph, the initial value of function C is 2

Hence, the function C has the greatest initial value

Rate of change

Rate of change is calculated as:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, the rate of change of function A is calculated as follows:

[tex]m = \frac{5 - 0}{2-0}[/tex]

[tex]m = \frac{5 }{2}[/tex]

[tex]m = 2.5[/tex]

The rate of change of function A is 2.5

The rate of change of function B is 3.

The rate of change of function C is calculated as follows:

[tex]m = \frac{3 - 2}{3-0}[/tex]

[tex]m = \frac{1}{3}[/tex]

The rate of change of function C is 1/3

Hence, the function B has the greatest rate of change
