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’s non linear and it’s decreasing

Answer:
A. Positive
Step-by-step explanation:
They ask us about the relationship between reading and grades.
First you have to go to the first part of the statement that says:
"Dr. Yancy conducted a correlation study in which she found that the more time children in her study read at home the better they performed in school"
In this case they tell us that there is a positive correlation, that the more you read the better your performance in school is.
Performance is your grades, and home study can be reading, so the score is positive in the second half, too.
