Question

Simple interest = P × r × t

Answer 1

Answer:

$18.

Step-by-step explanation:

We have been given that Joe borrowed $900 from Sam for six months. The interest rate charged by Sam is 4%.

We will use Simple interest formula to solve our given problem.

$I=PrT$, where,

$I=\text{Simple interest}$,

$P=\text{Principal amount}$,

$r=\text{Interest rate in decimal form}$,

$T=\text{Time in years}$.

Let us convert our given rate in decimal form.

$4\%=\frac{4}{100}=0.04$

12 months = 1 year.

1 month = 1/12 year.

6 months = 6/12 year = 1/2 year = 0.5 year.

Upon substituting our given values in simple interest formula we will get,

$I=900*0.04*0.5$

$I=900*0.02$

$I=18$

Therefore, Sam will earn $18 if he charge Joe a simple interest rate of 4 percent.

Answer 2

700 times 2 is right nothing besides that makes sense
