garri49 [273]

Answer:

$550.97

Step-by-step explanation:

The amortization formula will tell you the payment amount.

A = P(r/12)/(1 -(1 +r/12)^(-12t))

where A is the monthly payment, P is the principal amount of the loan, r is the annual interest rate, t is the number of years. Using your values, this is ...

A = $12,000(0.095/12)/(1 -(1 +0.095/12)^(-12·2)) ≈ $550.97

The amount of Gerald's payment is $550.97.

8. Lesly took a test with 30 questions. The ratio of correct answers to incorrect answers

Firlakuza [10]

Lesly got 14 answers correctly.

Let the correct answers be C.

Let the incorrect answers be I.

Given the following data:

Total number of questions = 30 questions.

Ratio of C to I = 7 : 8

C to I = 7 + 8 = 15

To find the number of answers she got correctly;

$C = \frac{7}{15}$ × $30$

$C = 7$ × $2$

Correct answers, C = 14 answers

Therefore, Lesly got 14 answers correctly.
