Florence invests £200 for two years at 5% compound interest paid yearly. Liam says that the interest that Florence will receive will be £20 is Liam right?

No, Liam is wrong

Step-by-step explanation:

Amount invested by Florence = £200

Formula for compound interest = P * (1 + R / 100)^Time period

P = £200

R = 5%

Time period = 2

£200 * (1 + 5/100) ^ 2

=> £200 * 1.05^2

=>£200 * 1.1025

=> £220.5

So the interest = 220.5 - 220 = 20.5

20.5 ≠ 20

Therefore, Liam is wrong.

Hope it helps :)

10 b/c 5*2 =10

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
