Answer:

$I=\$47.25$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the amount of money borrowed

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=9/12\ years\\ P=\$900\\r=0.07$

substitute in the formula above

$I=900(0.07(9/12))$

$I=\$47.25$
