Answer:
Stefanie bought 10 erasers
Step-by-step explanation:
We can establish the following equation:
TP = NP*PP + NE*EP
Where:
TP = Total price; (4.25)
NP = Number of pencil packages; (1)
PP = Pencil Package's Price; (1.75)
NE = Number of erasers; (What we are looking for)
EP = Erasers Price; (0.25);
Then:
4.25 = 1*1.75 + NE*0.25;
4.25 - 1.75 = NE*0.25;
2.5/0.25 = NE;
10 = NE.
It is said that 85% of the students liked reading mystery stories. This means the remaining 15% don't like to read these stories. If there are 30 students belonging to the second category, then the number of students who liked reading mystery stories is (30/0.15)*0.85 equal to 170 students out of 200 students.

Hi Avahosel2020!
To find the value of 
we need to simplify the equation:
25 = 12.5
To just get , we must divide 25 on both sides:
= 
<u>We can move the decimal one spot over and add a 0 to the denominator:</u>
= 
=
Simplifying!
= 
.
Thus, has the value of 
.
I think it is the 3rd one but I might be wrong...
