Answer 1

Answer:

Interest amount to $15.5.

Miguel must pay $515.5 Julio at the end of 6 months.

Step-by-step explanation:

Given :Miguel Rodriguez borrowed $500.

           He agreed to pay back in 6 months with simple interest at 6.2.  

To Find :How much will the interest amount to? What amount must Miguel pay Julio at the end of 6 months?

Solution:

Principal (P)= $500

Rate of interest(R)= 6.2%

Time= 6 months = 0.5 years

Formula : $SI = \frac{P \times R \times T}{100}$

$SI = \frac{500 \times 6.2 \times 0.5}{100}$

$SI = 15.5$

So,the interest amount to $15.5

Amount = Principal +Interest

Amount = $500+$15.5

Amount = $515.5

So, Miguel must pay $515.5 Julio at the end of 6 months.

Answer 2

he will pay $31 in interest after 6 months so after 6 months he will pay $531
