60 = 5(1.07)^x initial value:

a. 7%

b. 1.07%

c. 9.3%

d. 5

e. 60

growth or decay?

growth/decay rate?

a. 7%

b. 1.07%

c. 9.3%

d. 5

e. 60

Given:

The given equation is

To find:

The initial value and growth/decay factor.

Solution:

The general exponential growth/decay model is

    ...(i)

where, a is initial value, if r>0, then |r| is growth factor, if r<0, then |r| is decay factor and x is time.

We have,

It can be written as

       ...(ii)

On comparing (i) and (ii), we get

Here, initial value is 5 and growth factor is 0.07, i.e., 7%.

Therefore, the correct option for first question is d and correct option for second question is a.
