$5,400 at 3.5% for 6 months

A = $5.09

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.5%/100 = 0.035 per year.

Putting time into years for simplicity,

6 months / 12 months/year = 0.5 years.

Solving our equation:

A = 5(1 + (0.035 × 0.5)) = 5.0875

A = $5.09

The total amount accrued, principal plus interest, from simple interest on a principal of $5.00 at a rate of 3.5% per year for 0.5 years (6 months) is $5.09.
