Your vacation costs you $500 for the airline ticket plus $100 per day, d. How much would it cost for a 7-day vacation?

Answers

Answer:

1,200$

Step-by-step explanation:

500+700 = 1.200$

700 = 100 per day for 7 day vacation

Answer:

$1200

Step-by-step explanation:

So the equation will look like this if d is days and c is cost: c=100d+500 this is it because the $500 is only a one-time fee while $100 is the rate of change so it depends on the number of days you are on vacation. Now since we know how many days we have to go we can just plug it in d: c=100(7)+500

Simplify: c=700+500

Add: c=1200

Answer: $1200

4500 people attended a football game. If 25% of the people who attended were teenagers, how many teenagers attended the game?

Answers

Answer: 1,125

Step-by-step explanation:

We have to find out what is 25% of 4,500.

Let's subtract by thousands first. We have to subtract 75% of the thousands.

4,000 - 3,000 = 1,000

Now, we have to subtract 75% of 500.

500 - 400 = 100

Now, we have to subtract 75% of 100. We currently have 1,100.

100 - 75 = 25

Add 1,100 and 25.

1,100 + 25 = 1,125

Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 0 < x < 3.

Answers

Answer:  104/3

Note: in decimal form, this fraction converts to roughly 34.67

=========================================================

Explanation:

Highlight the rows that have x = 0 and x = 3. Cross out or cover the other two rows up.

The two rows that have x = 0 and x = 3 show y = f(x) = 4 and y = 108 respectively.

So we have the two points (0,4) and (3,108). We need to find the slope of the line through these points to find the average rate of change from x = 0 to x = 3.

Turn to the slope formula

m = (y2-y1)/(x2-x1)

m = (108-4)/(3-0)

m = 104/3

We cannot reduce the fraction further.

Using a calculator,

104/3 = 34.67 approximately
