Answer
${$2560.00}$
Work Step by Step
First remember that the formula for simple interest is $A=P(1+rt)$
wherein A is final amount, P is initial primary balance, r is annual interest rate, and t is time in years.
Next let us convert R percent to r decimal
r = R/100 = 10%/100 = 0.1 per year.
Putting time into years for simplicity,
8 months / 12 months(1 year) = 0.666667 years.
Solving our equation:
A = 2400(1 + (0.1 × 0.666667)) = 2560.00008
A = $2,560.00
The total amount accrued, principal plus interest, from simple interest on a principal of 2,400.00 at a rate of 10% per year for 0.666667 years (8 months) is 2,560.00.
