Answer:
Step-by-step explanation:
The formula for simple interest is
I = Prt
where I is the interest earned, P is the initial deposit, r is the rate in decimal form, and t is the time in years. For us,
I = 125(.03)(3) which gives us an interest amount of
I = 11.25
To find out how much money she has total after that interest builds up, we add that interest amount to the initial investement amount to get
125 + 11.25 = 136.25
