Based on the types of compounding and the interest rates, the following are true:
- Part A - The group will have $750
- Part B - The group will have $759.19
When using simple interest, the amount the group will have is:
<em>= Amount x ( 1 + rate x number of years )</em>
= 600 x ( 1 + 5% x 5)
= $750
When using compound interest, the group will have:
<em>= Amount x ( 1 + rate) ^ Number of years</em>
= 600 x ( 1 + 4%)⁶
= $759.19
In conclusion, compound interest yields more.

<span>2/3x -4=-2
-------------------
Add 4 to each side
</span><span>2/3x-4+4</span>=-<span>2+<span>4
2/3x = 2
-----------------------------
Multiply each side by 3/2
(3/2) * (2/3x) = (3/2) * (2)

The probability that Nathan is not allergic to penicillin is 1 - 0.75 = 0.25.
The probability that Nathan is not allergic to penicillin and the test predicts it is given by:
So, the ration is 17:3, you know that. Therefore, the change from # of students to the 17 is the same change as # teachers to 3. Knowing this, you also know that the total # of people ihas the same change as the total ratio. So 17+3 = 20. 740/20 = 37. So the change is 37. 3x37= 111 17x37=629
You can check to make sure this answer is correct by adding the two final numbers. 111+629 = 740. (Some find it easier to see lined up really pretty)
17 -- 3 total 20
x -- y total 740
