Walker is planning a summer vacation. he want to visit petrified national forest and meteor crater,arizona,the 5-year old impact site of the large meteor. on a map with a scale where 2 inches equals 75 miles, the two areas are about 1 and a half apart. what is the distance between petrified national forest and meteor crater?

56.25 miles

Step-by-step explanation:

Walker wants to visit petrified national forest and meteor crater.

On a map, a scale is 2 inches = 75 miles.

The national forest and meteor crater are about 1 and a half inches apart.

Let x miles be the actual distance between national forest and meteor crater.

Then

2 inches - 75 miles

inches - x miles.

Write a proportion:

Cross multiply

Or you can think in such way:

2 inches - 75 miles

1 inch - 37.5 miles

1/2 inch - 18.75 miles

1 1/2 inches - 37.5 + 18.75 = 56.25 miles

I think the answer would be best supported with an equation. Then everything will fall into place

Step-by-step explanation:

We have a pre-set amount of $800. That will not change.

The key word here is each. It costs $15 to print each yearbook. Each depends on how many yearbooks are bought.

We will use y to represent the amount of yearbooks bought, and t to represent the total cost.

Equation:

800 + 15y = t

Let's try an example:

The yearbook club finds that 50 people have decidedly bought yearbooks! They are so excited! But they have a problem. They don't know how much the whole thing is going to cost: the yearbook software cost AND the amount they must spend on printing each yearbook. What is the total cost?

So we have an equation: 800 + 15y = t. Now we just substitute in the numbers and voila! We get our answer. Let's solve!

800 + 15y      = t

800 + 15(50) = t      (y is the amount of yearbooks bought. 50 people

800 + 750     = t       bought yearbooks).

1150               = t      (t is the total cost of everything).

Our total cost is $1150! That is how much it'll cost to make all the yearbooks, including the yearbook software.

I hope this helps!
