Tanya [424]

Answer:

$r=0.05$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

A is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=3\ years\\ P=\$3,000\\I=\$450\\r=?$

substitute in the formula above

$450=3,000(3r)$

solve for r

$450=9,000(r)$

$r=450/9,000$

$r=0.05$
