Write a formula that will help you determine your total cost.
Let's let
t = cost of ticket
f = cost of food
b = cost of bus (one way)
C = total cost
Your friend asks you to go to the
amusement park for a day. You'd like to
go, but you need to find the total cost.
You'll need to pay for a ticket and food,
plus bus fare to get to the park and
back. (Remember, you'll need to take
the bus to the amusement park and
home, so you'll need to double the cost
of the ticket.)
Enter the correct answer.

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
