Adrian has 256 money by the end of month 4, at month 1 he had saved 4 dollars, use an exponent in an expression to represent how

ioda

Answer:

The required expression would be $4(4)^{t-1}$

Step-by-step explanation:

Since, the amount formula is,

$A=P(1+r)^t$

Where,

P = invested amount,

t = number of periods,

r = rate per period,

Given,

The invested amount at month 1, P = 4,

Number of periods from month 1 to month 4, t = 3

Amount at the end of fourth month, A = 256.

By substituting the values,

$256=4(1+r)^3$

$64=(1+r)^3$

$4=1+r$

$r = 4-1=3$

Hence, the amount of money at the end of t months.

$A=4(4)^{t-1}$
