Answer:
so u multiply negative four times nagative 1.5
9514 1404 393
Answer:
Step-by-step explanation:
Let x represent the amount invested at 13%. Then (3x+199) is the amount invested at 12%. The total interest earned in 1 year is ...
(13%)(x) +(12%)(3x+199) = 1561.50
0.49x +23.88 = 1561.50 . . . . simplify
0.49x = 1537.62 . . . . . . . . . . subtract 23.88
x = 3138 . . . . . . . . . . . . . . . . divide by 0.49
3x+199 = 9613
$3138 was invested at 13%; $9613 was invested at 12%.
Uh for the second question, his height in decimal form would be 4.75, kind sir.
Hope this helped,
Simple Interest:
I = P x r x t
I = 8000 x 0.15 x 2
I = 2400
Compound Interest:
A = P(e^rt)
where e is the Euclid’s constant
and A is the total amount with interest
A = 8000(e^0.15(2))
A = 10799 (rounded up)
Therefore compound interest is 2799.
The difference:
compound - simple = 2799 - 2400
Answer is rs 399.
