The formula for the amount of money in an interest-bearing account that is compounded is

where A is the total amount in the account, p is the amount of principal invested, r is the interest rate as a decimal number, n is the number of times per year interest is compounded, and t is the number of years. Using our information we have:

Divide both sides:
Answer:
42
Step-by-step explanation:
Test worth = 50
To obtain a grade percent = 84%
Score to obtain = x
Using the expression :
84% of test worth = x
84/100 * 50 = x
0.84 * 50 = x
42 = x
Score to obtain = 42
Answer:
B
Step-by-step explanation:
The graph passes through (0,0) so this point HAS to satisfy the equation.
Let's check this. We put 0 into both x and y and check if the equation holds true:
A) y = -2 NO!
B) y = 0 YES!
C) 1 = 18 NO!
D) y = -2 NO!
Definitely the equation of this graph is B.
Note: If there were more than one "yes" in our checking, then we would have taken another point and boiled it further down. But we didn't need to.
=(-17) - 4
=(-17) + (-4)
=(-21)
