A = P + I
A is the new value
P is the initial value
I is the interest
I = PRT
R is the rate in decimal
T is the time
Joy has $68020
P = 68020
The account earns 13% annually
R = 13% = 13/100 = 0.13
The time is 5 years
T = 5
Let us find I, then A
I = 68020(0.13)(5)
I = 44213
Now let us find A
A = 68020 + 44213
A = $112233
She has $112233 in 5 years
