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
