Answer:

t = 4 years

Explanation:

we know that

The simple interest formula is equal to

A = P(1+rt)

where

A is the Final Investment Value

P is the principle amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

t=? years

P= $5,000

A= $6,000

r= 5% = 5/100 = 0.05

substitute in the formula above

6,000 = 5,000 (1 + 0.05t)

solve for t

Simplify

Divide by 5,000 both sides

1.2 = 1 + 0.05t

subtract 1 both sides

0.05t = 1.2 - 1

0.05t = 0.2

divide by 0.05 both sides

t = 4 years
