1. $800 x 8 yrs. = $6,400
2. the interest = $704
3. total would be $7,104
btw to for step 2 this is what i did:
$800 x 0.11 (the interest rate in a decimal form)= $88 then $88 x 8 years= 704
I think that it's 13.20? not very sure!

Answer:

Step-by-step explanation:
Use:



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
