Plug in what we know:
[tex]\sf~622.5=(12450)r(1)[/tex]
Multiply:
[tex]\sf~622.5=12450r[/tex]
Divide 12450 to both sides:
[tex]\sf~r=0.05[/tex]
Multiply by 100:
[tex]\sf0.05\times100=5\%[/tex]

Answer:
5%
Explanation:
% she earned in interest can be calculated by calculating the % of increase in the balance
We have:
Original balance = $12,450
Amount of interest = $622.5
This means that:
new balance = 12,450 + 622.5 = $13,072.5
Now, we can get the percentage of increase:
% of increase = [tex] \frac{Value_n_e_w - Value_o_l_d}{Value_o_l_d} *100 [/tex]
Substitute with the values we have to get the percentage of interest earned as follows:
% of interest earned = [tex] \frac{13072.5 - 12450}{12450} * 100 [/tex] = 5%
