Answer:
The simple interest is $11,212.5 and the equation to determine Josh's simple interest is I = PRT/100
Step-by-step explanation:
The formula for calculating simple interest is expressed as;
SI = Principal * rate * time/100
SI = 50,000 * 6.9*39/100*12
SI = 500*6.9*39/12
SI = 134,550/12
SI = 11,212.5
Hence the simple interest is $11,212.5 and the equation to determine Josh's simple interest is I = PRT/100
P is the amount borrowed
R is the interest rate
T is the time in years
