a. The interest earned will be $36.
b. The account balance will be $336.
Step-by-step Explanation:
Step 1:

4% of $300 = 
Step 2:
So for every year, the interest of $12 is added into the account. To calculate total interest we multiply this interest amount and the number of years.

Answer:
(X,Y)(18,12)
Step-by-step explanation:
x + y = 30
2x + 4y = 84
___________
2x+2y=60
2x+4y=84
_________
-2y=-24/-2y
y=12
2x+4(12)=84
2x+48=84
2x=84-48
2x/2=36/2
X=18
