On each weekly spelling test, the students in Mrs. Ruiz's class record how they do in comparison to the week before.
For example, if they spell two more words correctly this week than last week, then they put a +2 in the corner of their
paper. If they spell two less words correctly this week than last week, then they put a -2 in the corner of their paper,
After collecting the papers, Mrs. Ruiz notices that the first four papers had the following marks:
Student A-1
Student B: 0
Student C-3
Student D:2

Which student's score changed the most from last week?

Student A
Student B
Student D
Student C

Student C

Step-by-step explanation:

* Student C *

If we were to take a look at the problem we would see that the greatest difference would be the greatest difference from 0, either positive of negative;

Student A: 1 from 0,

Student B: 0 from 0,

Student C: 3 from 0,

Student D: 2 from 0

As we see from the results, Student C has the greatest difference from before

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
