Answer 1

Answer:

Initial value is 5, Growth, 7%

Initial value is 60, Decay, 7%

Step-by-step explanation:

Growth and decay are given respectively by $A=P(1+r)^x\\or\\A=P(1-r)^x$. Growth adds to 1 by its percent. Decays subtracts from one its percent.

Since the left has a rate greater than 1 it is growth and the amount above is it's percent as a decimal. We convert by multiplying 0.07 by 100 which equals 7%. The right has a rate less than 1 and is decay. The amount below 1 has been found by subtracting the rate. So we subtracted -0.07 to get 093. Then 0.07 is our rate and we multiply by 100 to get -7%.

The initial value is P and is always P. On the left, 5 is in the P position. On the right, 60 is in the P position.
