Charmaine= x
William=x+3
3 times Charmaine = 3x
2times William = 2x+6
5x+6=76
5x=76-6
5x=70
X=14
Charmaine is 14
William is 3 years older so is 17
Check:
17x2= 34
14x3=42
34+42=76
So Charmaine is 14
William is 17

Answer:
$4,309.12
Step-by-step explanation:
The computation of the interest earned is given below:
But before that the amount would be
Amount = Principal × (1 + rate of interest)^number of years
= $6,000 × (1 + 0.07)^8
= $6,000 × 1.07^8
= $10,309.12
Now the interest earned is
= Amount - principal
= $10,309.12 - $6,000
= $4,309.12
