You deposit 800 dollars into your savings account how much simple interest will 800 dollars earn in 6 months at 7.25%

First, converting R percent to r a decimal

r = R/100 = 7.25%/100 = 0.0725 per year,

putting time into years for simplicity,

6 months : 12 months/year = 0.5 years,

then, solving our equation

A = 800 (1 + (0.0725 * 0.5)) = 829

A = $ 829.00

The total amount accrued, principal plus interest,

from simple interest on a principal of $ 800.00

at a rate of 7.25% per year

for 0.5 years (6 months) is $ 829.00.
