Answer: 7.25%
Step-by-step explanation:
There are a few ways to do this, but the easiest might be to set up a proportion:
321.75/300 = x percent/100 percent
Now cross multiply;
300x = 321.75(100) = 32,175
Divide both sides by 300 to solve for x:
300x/300 = 32,175/300
x = 107.25 This means that the tip was 7.25% on top of the $300 meal.

Answer:
495 combinations of 4 students can be selected.
Step-by-step explanation:
The order of the students in the sample is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
How many combination of random samples of 4 students can be selected?
4 from a set of 12. So
495 combinations of 4 students can be selected.
Answer:
$21.17
Step-by-step explanation:
Simple Interest=P(1+r)^t
Compounded Interest=P(e^rt)
SI=668*(1.0925)^5
SI=1039.64
CI=668(e^(0.0925*5))
CI=1060.81
1060.81-1039.64=21.17
So the difference is $21.17, thus doing compounded interest is better.
