The annual rate of decay is 13 %.

g = 18(0.5)^(x/5)

g/18 = (0.5)^(x/5)

ln(g/18)  = (x/5)ln0.5 = -0.139x

The annual rate of decay = 13.9 %.

Answer:

The annual rate of decay is 13 %.

Step-by-step explanation:

g = 18(0.5)^(x/5)     were going to move the 18 and  divide x/5 (which cannot be divided)

g/18 = (0.5)^(x/5)

ln(g/18)  = (x/5)ln0.5

-0.139x
