Answer:
The answer is option (C), T = 100 • 0.1 • 10
Step-by-step explanation:
Total interest (T) earned after a 10 years can be expressed as;
Total interest (T)=Principal amount×interest rate×Number of years
where;
Total interest=T
Principal amount=$100
Interest rate=10%=10/100=0.1
Replacing;
T=100×0.1×10
The equation for calculating the total interest amount after 10 years can be written as;
T = 100 • 0.1 • 10
