Answer:
1.
A = PHP92,075.00
I = A - P = PHP 19,575.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year.
Solving our equation:
A = 72500(1 + (0.09 × 3)) = 92075
A = PHP 92,075.00
The total amount accrued, principal plus interest, from simple interest on a principal of PHP 72,500.00 at a rate of 9% per year for 3 years is PHP 92,075.00
2.
A = PHP 3,165.00
I = A - P = PHP 165.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 11%/100 = 0.11 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 3000(1 + (0.11 × 0.5)) = 3165
A = PHP 3,165.00
The total amount accrued, principal plus interest, from simple interest on a principal of PHP 3,000.00 at a rate of 11% per year for 0.5 years (6 months) is PHP 3,165.00.
3.
A = PHP62,660.00
I = A - P = PHP 14,460.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year.
Solving our equation:
A = 48200(1 + (0.12 × 2.5)) = 62660
A = PHP 62,660.00
The total amount accrued, principal plus interest, from simple interest on a principal of PHP 48,200.00 at a rate of 12% per year for 2.5 years is PHP 62,660.00.
