Answer:
$49,126.87
Step-by-step explanation:
Given data
Principal= $33,000
rate= 6.75%
Time= 6 years
First, convert R as a percent to r as a decimal
r = R/100
r = 6.65/100
r = 0.0665 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 33,000.00(1 + 0.0665/12)^(12)(6)
A = 33,000.00(1 + 0.005541667)^(72)
A = $49,126.87
Hence the final amount is $49,126.87
