Answer:
$5.24
Step-by-step explanation:
First, we need to find how many of each coin type we have. For pennies and dimes, we can take the percentage and divide by two for the number of coins.
18 / 2 = 9 pennies
36 / 2 = 18 dimes
We also know that there are three more nickels than there are dimes.
9 + 3 = 12 nickels
We can subtract the total number of nickels, pennies, and dimes from the total number of coins to get the number of quarters.
50 - 39 = 11 quarters
Then, we do the math to find the value.
9 x 0.01 = 0.09
18 x 0.10 = 1.80
12 x 0.05 = 0.60
11 x 0.25 = 2.75
2.75 + 1.80 + 0.60 + 0.09 = $5.24
Their sum would be of odd number....
Hello there! So, the formula for compound interest is P(1 + r/n)^nt. P = principal, r = rate, n = number of times compounded per year, and t = time in years.
a. Just by looking at the numbers, I would say that Gavin should take the first option of 9% compound interest annually.
b. I say this, because you're gonna earn a lot more. Just by solving the question for the amount in 5 years for each account, the first opinion will earn you $3,077.35, and the other option will only give you $2,265.42 in 5 years. Keep in mind that compounding quarterly means 4 times per year. With a low interest rate, it's no surprise that the first option would be a better choice.
Answer: There are 312 people who named neither blue nor red as their favorite color.
Step-by-step explanation:
Since we have given that
Total number of people who are surveyed = 7
Number of people who named blue as their favorite color = 4
According to question, one out of three named 'red'.
So, Out of seven people , number of people who named neither blue nor red as their favorite color is given by
There if there are 1092 people who were included in the survey , then we need to find the number of people who named neither blue nor red as their favorite color.
Hence, there are 312 people who named neither blue nor red as their favorite color.
