4,331 times 8 (semiannual for 4 yrs) = 34,648
34,648 + 5.5% = 36,553.64
to find interest:
36,553.64 - 34,648 = 1,905.64
THE INTEREST RATE IS $1,905.64
3/5(divided)9/7
3/5x7/9

Answer:
B.
Step-by-step explanation:
x represents the amount of guests going to the birthday party, with the amount of money per guest being 12. You would multiply those two together, but as we do not know the total amount of guests, we keep it as a variable. 125 is the amount before the guests even know about the party, so therefore, you would need to use that equation.
For the 2nd question......is it correct????? Because the area of square is s.s and area of rectangle is l.b
Answer:
120
Step-by-step explanation:
We are given that the function for the number of students enrolled in a new course is 
.
It is asked to find the average increase in the number of students enrolled per hour between 2 to 4 hours.
We know that the average rate of change is given by,
,
where f(x)-f(a) is the change in the function as the input value (x-a) changes.
Now, the number of students enrolled at 4 = f(4) = 
= 255 and the number of students enrolled at 2 = f(2) = 
= 15
So, the average increase 
= 
= 
= 120.
Hence, the average increase in the number of students enrolled is 120.
