Answer:</u></h3>
Option: C is the correct answer.
$ 1.50 is the cost of 1 eraser.
<h3><u>
Step-by-step explanation:</u></h3>
Alicia bought a notebook and several erasers at the student store.
Let the cost of 1 eraser=$ x.
Now from the scatter plot we could see that when Alicia did not bought any eraser then her total cost =$ 2.
That means cost of a notebook=$ 2.
Now when she buys a notebook and two eraser then she pays=$ 5.
i.e.
Total cost=cost of notebook+ 2× cost of 1 eraser
Total cost=cost of notebook+2×x
i.e.
5=2+2x
⇒ 2x=5-2
⇒ 2x=3
⇒ x=1.5
Hence, cost of one eraser is:
$ 1.50
Hey!
Dean's family has been traveling on the same speed for two days, so to find how far you will need to travel you will need to find how far they are traveling in one hour..
To find this you will need to set up a proportion...
3/195 = 1/x
Solve this proportion by cross multiplying and then dividing..
195 * 1 = 195/3 = 65
This tells you that they are traveling 65 miles per hour. Now with this you will simply have to multiply 65 by 5 to tell you how far they would be traveling in 5 hours with the given speed...
65 * 5 = 325
Your answer of 325 miles tells you how far they traveled.
Hope it Helped!

First, let's identify the like terms.
2 and 17
2n and 3n
Next, you would need to combine them. Ex: Add 2n to both sides, and subtract 17 from both sides.
2 - 2n = 3n + 17
2 = 5n + 17
-15 = 5n
Now, all you would need to do is isolate the n. To do this, you would divide both sides by 5.
-15 = 5n
-3 = n
n = -3
The solution would be -3.
I hope this helps!
