The wife made 33,500 and the husband made 29,500
-4x +12 -12 = -4 -12
-4x = -16
x = 4
The standard compound interest formula is
Future value after x years with an annual interest of i
=Present Value (1+i)^x [which is an exponential function]
for given present value of $360. interest=0.03 (3%) and a total of x years, above equation reduces to
Future value after x years
=360(1.03^x)
The answer is 1-28/2992/8 ow
