Ответ:
Ravi : x marbles
Sam : 3x marbles
Elliot: x + 2
x + 3x + (x + 2) = 92
5x + 2 = 92
5x = 92-2= 90
x= 90/5 = 18
The answer is 18.
Ответ:
$7200 in the fund rose 6% n $2800 in the fund rose 9%
Step-by-step explanation:
let x be the amount in the fund rose 6%
gain in one year=x*6%=0.06x
total amount is 10000
so amount in the fund rose 9% = 10000-x
gain in one year=(10000-x)*9%=900-0.09x
total gain=0.06x+900-0.09x=900-0.03x
=684
900-684=0.03x
0.03x=216
x=7200
the other fund amount=10000-7200=2800
