Hello Grossjoann, if you have 3,500$ with a interest rate of 15.75% at the end of the month you will get 44.10$ below will explain,
Answer: I = $ 44.10
Equation: I = Prt Calculation: First, converting R percent to r a decimal r = R/100 = 15.75%/100 = 0.1575 per year, putting time into years for simplicity, 1 months ÷ 12 months/year = 0.08 years, then, solving our equation
I = 3500 × 0.1575 × 0.08 = 44.1 I = $ 44.10
The simple interest accumulated on a principal of $ 3,500.00 at a rate of 15.75% per year for 0.08 years (1 months) is $ 44.10.
