77+72=149
149/2=74.5
through the process of elimination, I found that Jim needs to get an 88 or higher to receive an average of 79 or greater.
77+72+88=237
237/3=79
Answer:
Step-by-step explanation:
Since it is simple interest, you have to use the formula I = Prt.
(I is interest, P is principal (the starting amount), and r is the & rate as a decimal.
So, the interest would be
I = 543,300 (0.048) (2) = $52,156.80
The balance is the total amount. The balance would be the starting amount plus the interest.
Balance = 543,300 + 52,156.80 = $595,456.80
