Ted:
4,000 @ 4.5% interest compounded annually
Alan:
1,000 @ 6% interest compounded annually
Rule of 72: divide 72 by the compound annual interest rate
Ted: 72/4.5% = 16 years
Alan: 72/6% = 12 years
<span>Alan will win. It will take 12 years.</span>
Answer:
$375.32
Step-by-step explanation:
100% - 40% = 80%
80/100 = 0.8 (multiplier)
521.28 x 0.8 = 417.024
417.024 to 417.02 (2 d.p.)
100 - 10 = (ans)/100 = 0.9
417.02 x 0.9 = 375.318
$375.32
Answer:
x = 4
Step-by-step explanation:
4x+2=18
subtract 2 to both sides
2 cancels out
4x=16
divide both by 4
4 cancels out
x= 4
We just take the square root of 16384.
√16384 = 128
128^2 = 16384
Best of Luck!
