Question

1) A drive-in theatre charges $2 per vehicle plus $1 for every person in the vehicle. Find the charge for a bike with two people, by forming the equation. 2) Using the variable "a" to represent a number, write an inequality for "two times a number decreased by four that is at least five times a number".

Answer 2

is a bike considered a vehicle|||:::>???

Answer 3

in this question it is i guess lol

Answer 4

How much do you think it would be?

Answer 5

four dollars

Answer 6

Yup, do you know how to write the equation?

Answer 7

not really no

Answer 8

Well for each vehicle the $2 charge doesn't change. So we know that the price P for a group of people is going to be
P = 2 + ?
If we have a car with one person, P would be three dollars. If we have a car with two people, P would be four dollars and so on.
Do you have any idea what the '?' will be?

Answer 9

2

Answer 10

In general, If we have x people how much will it cost for them (not including the vehicle) to get in to the theatre?

Answer 11

2$ so it should be 1x right p=$2=1x

Answer 12

i meant $2+1x=4

Yup :)

Answer 14

Answer 17

Yup

What do you think "two times a number decreased by four" is?

Answer 18

2x-4

Answer 19

and what do you think "five times a number" is?

Answer 20

5a

Answer 21

2a-4(5a)

Answer 22

Yup (be sure to use 'a' on both sides)

We have to account for the 'at least' statement

Answer 23

did i not use a on both sides?

Answer 24

2a-4 '?' (5a)

It will be <, <=, =, >, or >=

Answer 25

Was talking about when you used x in "2x-4"

Answer 26

ooh thats the inequality part so maybe we could use >or= to 5a

Answer 27

Correct :)

Answer 28

okay so the inequality is 2a-4<= 5a

Answer 29

2a-4 >= 5a

Answer 30
