Answer:
The amount invested at 9% is $93000
The amount invested at 10% is $303000
Step-by-step explanation:
Let the amount invested at 9% interest rate be x
And the amount invested at 10% rate be y
Simple Interest from x in a year = 0.09x
Simple Interest from y in a year = 0.1y
But y = 24000 + 3x
And the sun of the interests, 0.09x + 0.1y = 38670
Now we have a simultaneous eqn
y = 24000 + 3x (eqn 1)
0.09x + 0.1y = 38670 (eqn)
Substitute y into eqn 2
0.09x + 0.1(24000 + 3x) = 38670
0.09x + 2400 + 0.3x = 38670
0.39x = 38670 - 2400
x = 36270/0.39 = $93000
y = 24000 + 3x = 24000 + 3 × 93000 = $303000
Solution:
4/11 = 0.36
3/14 = 0.21
He still needs to play 0.15 of an hour or 3/20 of an hour.
Given facts - Amount he has to play, and the amount he played.
Question - For how long does he need to practice to meet the required time.
Hidden question - There is nothing hidden
Operations used - divisions (not necessary), subtractions and conversion (only if used division).
Number sentence - 4/11 - 3/14 = x
Answer - 3/10 of an hour.

➷ Just substitute the given value into anywhere you see the term x:
2 x 4^2 + 12
Follow the PEMDAS rule:
(calculate the exponential first)
4^2 = 16
Now we have:
2 x 16 + 12
(now the multiplication needs to be calculated)
16 x 2 = 32
Now we have:
32 + 12
Add them together to get the answer:
44 <== this is the answer
