Answer:
274.576 + 8400 = $8674.576
Step-by-step explanation:
Here, Number of days = 21 + 31 +30 +31 +20 = 123
We know that,
[tex]Simple Interest = \frac{P\timesT\timesR}{100}[/tex]
where, P = Principle = 8400
T = time = 123 ÷ 365
R = Rate = 9.2
⇒ [tex]Simple Interest = \frac{8400\times123\times9.2}{365\times100}[/tex]
⇒ Simple Interest = 274.576
Thus, total amount Jane has on 20 August = 274.576 + 8400 = $8674.576
