Answer:

15000(1.003425)^12t ;

4.11%

4.188%

Step-by-step explanation:

Given that:

Loan amount = principal = $15000

Interest rate, r = 4.11% = 0.0411

n = number of times compounded per period, monthly = 12 (number of months in a year)

Total amount, F owed, after t years in college ;

F(t) = P(1 + r/n)^nt

F(t) = 15000(1 + 0.0411/12)^12t

F(t) = 15000(1.003425)^12t

2.) The annual percentage rate is the interest rate without compounding = 4.11%

3.)

The APY

APY = (1 + APR/n)^n - 1

APY = (1 + 0.0411/12)^12 - 1

APY = (1.003425)^12 - 1

APY = 1.04188 - 1

APY = 0.04188

APY = 0.04188 * 100% = 4.188%

PLEASE HELP!! MATH FINAL
DaniilM [7]

Answer:

12 dimes, 8 nickels

Step-by-step explanation:

1. Set up an equation. Since we know the relationship between how many dimes and how many nickels that he has, we can create values for them.

2. Say that the number of nickels is x, so the number of dimes would be 2x-4.

3. Since we know that all of the coins that he has is 20 coins, we can say that 2x-4+x=20.

4. Solve the equation. We get 3x=24, and x=8.

5. That means that the number of nickels is 8, and the number of dimes is 2(8)-4, which is 12.

Answer: Timmy has 12 dimes and 8 nickels.

Misha Larkins [42]

Answer: 500

Step-by-step explanation:

The remainder of the question is:

How many units does the company need to sell to reach the target profit?

The required sales to break even will be calculated as:

= (Fixed cost + Required profit) / ( Price per unit - Variable cost)

= (120000 - 80000) / (100 - 20)

= 40000/80

= 500

The company needs to sell 500 units.
