Answer:
π
Step-by-step explanation:
The standard form of the sine function is
y = a sin(bx + c)
where a is the amplitude, period = 
and
phase shift = - 
here b = 
, c = - 
phase shift = - 
= × 2 = π
Principal amount = 12,000
Annual interest rate (r) = 6.99% = 0.0699
Time (years) = 4 years
Number of installments (t) = 12*4 = 48 months
Monthly payment, A = P/D
Where,
D= {(1+r/12)^t-1}/{r/12*(1+r/12)^t} = {(1+0.0699/12)^48-1}/{0.0699/12(1+0.0699/12)^48} = 42.47
Therefore, A = 12000/42.47 = 282.59
Total payments after 4 years = 282.59*4*12 = 13,564.17
Interest owed = 13,564.17 - 12,000 = 1,564.17
1/7 * 42/1
5 * 42 = 210
7 * 1 = 7
210/7 = 30
30
Answer:
214
