Answer:

Miguel pay amount to Julio at the end of 6​ months $206.8

Step-by-step explanation:

Given : Miguel Rodriguez borrowed ​$200 from his brother Julio to pay for books and tuition. He agreed to pay Julio in 6 months with simple annual interest at 6.8​%.


To Find : ​a) How much will the interest amount​ to?


​b) What amount must Miguel pay Julio at the end of 6​ months?


Solution :

Formula for simple interest :

S.I. = principal*rate*time

Where rate is in decimal

Time is in years

So, rate of interest = 6.8 % = 0.068

Time = 6 months = \frac{6}{12} = 0.5 years

Principal = $200

Thus S.I. = 200*0.068*0.5

S.I. = 6.8

Now To calculate  amount must Miguel pay Julio at the end of 6​ months

Amount = principal +Simple interest

Amount = 200+6.8 =206.8

Hence the simple interest is $6.8

And Miguel pay amount to Julio at the end of 6​ months $206.8
