Let 'x' be the problems worth 2 points.
Let 'y' be the problems worth 3 points.
Since, there are 38 total problems.
So,
(equation 1)
x = 38-y
Since, a perfect score is 100 points.
So,
(equation 2)
Substituting the value of 'x', we get



y = 24
x+y = 38
x = 38-24 = 14
So, 14 problems are worth 2 points and 24 problems are worth 3 points.
1. 74%
2. 15%
3. 9%
4. 61.7%
5. 83.4%

I'm not sure if this is right because I haven't done expanded form in years. If it isn't, I'm sorry.
Answer:
The amount the $20.000 will be worth in 17 years at compound interest is $65068.443
Step-by-step explanation:
Here we have the Principal, P = $20,000.00
The annual interest rate, r = 7% = 0.07
Time , t = 17 years
Number of compounding period per year, m = quarterly = 4
The compound interest can be found from the following formula;

Therefore, by plugging the values of the equation parameters, we have;

Therefore, the amount the $20.000 will be worth in 17 years at compound interest = $65068.443.
