Mean is the average....so you add all the numbers and then divide by how many numbers there were.
12 + 13 + 15 + 28 + 28 +30 + 42 = 168
since there are 7 numbers, you divide 168 by 7.
168/7 = 24
Therefore, 24 is the mean.

Answer:
c. $467.29
Step-by-step explanation:
The total of balances is $9360. The payment can be computed using the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^-n)
where A is the monthly payment, P is the principal (total balance), r is the annual rate, and n is the number of months.
Filling in your numbers, we have ...
A = $9360(0.18/12)/(1 -(1 +0.18/12)^-24) ≈ $467.29
Frank's monthly credit card payment will be $467.29.
The answer would be B 21/4
So there are 8 counters out of 20 which are yellow. so that is 8/20 which is simplified to 2/5
so the answer is 2/5
