Answer:
$594.03
Step-by-step explanation:
Using the exponential function;
A = Pe^-rt
Principal = $960
Rate r = 12% = 0.12
Time t = 4years
Substitute
A = 960e^-(0.12*)*4
A = 960e^-0.48
A = 960(0.61878)
A = 594.03
HEnce the worth after 4years will be $594.03
Distribute the 2 on the left to get 2e + 8 = 8e - 20
Add 20 to both sides and subtract 2e from both sides.
28 = 6e
Divide both sides by 6.
e = 14/3
