Ratio = 1:3
or in other words = sale price:original price
Therefore, it'd look like this = sale price:$81
So to work out the original price, you'd do $81 divided by 3 (81 ÷ 3 = $27).
The sale price is $27..

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
Their least common multiple is 90 .
90 = 5 x 18
90 = 2 x 45
Answer:
4,321
Step-by-step explanation:
This is the answer because:
1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1
2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place
3) Then, 2 is the other bigger number; therefore, the tens place is 2
4) Finally, the last number remaining is 1, which is in the ones place
Therefore, the answer is 4,321
Hope this helps!
