Tyler's mom purchased a savings bond for tyler. the value of the savings bond increases by 4% each year. one year after it was purchased, the value of the savings bond was $156. find the value of the bond when tyler's mom purchased it. explain your reasoning (plz hurry)

The value of the bond when Tyler's mom purchased it was $150

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

where

a is the initial value (y-intercept)

b is the base

r is the rate

b=(1+r)

In this problem

r=4%=4/100=0.04

b=1+0.04=1.04

substitute

where

x is the number of years since the savings bond was purchased

f(x) is the value of the savings bond

For x=1

f(x)=$156

substitute

Solve for a

therefore

The value of the bond when Tyler's mom purchased it was $150
