Answer:

simple interest is $6.8

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

Which inequality is represented by this graph? Also, if someone could tell me how this works that would be great :D

inysia [295]

Answer:

y > -1/6 x+1

Step-by-step explanation:

The graph line is dotted. Dotted lines means greater than or less than. ( <, >)

Solid lines means less than or equal to or greater than or equal to (≤,≥)

Since the graph is shaded above the line, that means y is greater than the line. If it were shaded below the line, y would be less than.

y > -1/6 x+1
