Question

find the amount and compound interest
p=4000
rate=7.5
duration=2​

Answer 1

Answer:

Amount = 4622.5

Compound Interest = 622.5

Step-by-step explanation:

$A = P {(1 + \frac{ R}{100}) }^{N} \\ A = 4000 {(1 + \frac{7.5}{100} )}^{2} \\ A = 4000( { {1.075)}^{2} } \\ A = 4000 \times 1.155625 \\ \large{ \boxed{A = \underline{ \underline{4622.5}}}} \\ \\ C. \: \: I.= A- P \\ \: \: \: \: \: = 4622.5 - 4000 \\ \large{ \boxed{ = \underline{ \underline{622.5}}}}$
