Answer:
$3.23
Step-by-step explanation:
Given that,
Principal, P = $2,000
Rate of interest, r = 1.96%
Tie, n = 1 month = (1/12) years
The formula of compound interest is given by :
![CI=P[(1+\dfrac{R}{100})^n-1]\\\\CI=2000\times [(1+\dfrac{1.96}{100})^{1/12}-1]\\\\CI=3.23](https://tex.z-dn.net/?f=CI%3DP%5B%281%2B%5Cdfrac%7BR%7D%7B100%7D%29%5En-1%5D%5C%5C%5C%5CCI%3D2000%5Ctimes%20%5B%281%2B%5Cdfrac%7B1.96%7D%7B100%7D%29%5E%7B1%2F12%7D-1%5D%5C%5C%5C%5CCI%3D3.23)
So, the interest will she earn at the end of 1 month is $3.23
Answer:
B. 0.73
Step-by-step explanation:
Add all numers so the first is 2/10 = 0.2
then 35/100 = 0.35
and then 16/100 = 0.16
finally 2/100 = 0.02
Now add all decimals which is equal to 73/100 = 0.73 and that's your answer.

Answer: 188 children and 200 adults were admitted
Step-by-step explanation:
Let x represent the number of children that were admitted.
Let y represent the number of adults that were admitted.
On a certain day, 388 people entered the park. It means that
x + y = 388
The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected on that day totaled $1736. It means that
2x + 6.8y = 1736- - - - - - - - - - 1
Substituting x = 388 - y into equation 1, it becomes
2x + 6.8y = 1736
2(388 - y) + 6.8y = 1736
776 - 2y + 6.8y = 1736
- 2y + 6.8y = 1736 - 776
4.8y = 960
y = 960/4.8
y = 200
x = 388 - y = 388 - 200
x = 188
It is 5.8 that is the answer
