An amusement park charges $8 for parking in addition to $1.25 per ride ticket. Write an equation to represent the total cost to visit the amusement park, then find the number of rides a person can go on, if they have $30. Identify your variables.

Answer:

Amount of rides = (30 - 8)/1.25

Answer:

c = 8 + 1.25r

the unit used is dollars

r = the amount of ride tickets purchased

c = total cost

a person could could go on 17 rides with 30$

Step-by-step explanation:

To develop the equation:

1. first, you want your total cost on one side. That is c (c =)

2. second, you need to identify the variable that changes the cost in the equation. That would be the amount of ride tickets because it changes the total cost based on how many a person buys. (c = 1.25r)

3. third, you add the variable that never changes, which is the eight dollars for parking (c = 1.25r +8)

In order to solve for a specific amount of money, you plug in the amount in place of your total cost (c) variable. In this case, you would solve 30 = 8 + 1.25r

It would look something like this:

30 = 8 +1.25r

(subtract 8 from both sides)

22 = 1.25r

(divide each side by 1.25)

r = 17.6

(round down because you can't buy a ride ticket with only 60 cents)

and you're done!

hope that helps!

Linda randomly surveyed 20 teachers at her school about whether they prefer chalkboards or dry erase boards. She repeated the survey three times with three different sets of teachers.

A 3-column table with 3 rows. Column 1 has entries Sample 1, Sample 2, Sample 3. Column 2 is labeled Chalk with entries 12, 9, 1. Column 3 is labeled Dry Erase with entries 8, 11, 19.

Which pair of Linda’s samples seems to have the lowest variability and, therefore, are representative samples?


samples 1 and 2
samples 1 and 3
samples 2 and 3
