Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

I=Prt

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

I=Pr(3)\\

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

I=\frac{Pr(4)}{12}

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

I=\frac{Pr(45)}{365}
