B. You would need to multiply 7% and 24 and you should get 1.68 and that’s how much money you are paying in taxes then add the 1.68 to the $24 and you get $25.68
M and n are both numbers to this problem
On the right side we have st which is the same as s*t or s times t
We want to undo the multiplication that is happening to s, so we have to divide both sides by t
d = s*t
d/t = s*t/t ..... divide both sides by t
d/t = s
s = d/t
Answer: Choice A)
Solution: Yes, the random variable y will have a binomial distribution. Because there are two possible outcomes 1. number of days of rain and 2. number of days of no rain.
The parameters of binomial distribution are
and 
The parameter n is given as the number of day's under consideration.

The parameter p is not given, but it can be estimated by number of days it rained divided by the total number of days under consideration.
