Answer:
The difference in the amount of interest she would have to pay for the two loans is $1,400
Step-by-step explanation:
The amount of loan Holly is taking out, P = $10,000
The choices available for the loan are;
1) Loan duration, T₁ = 4-year
Interest rate, R₁ = 4%
2) Loan duration, T₂ = 6-year
Interest rate, R₂ = 5%
For the first choice, we have;
The simple interest, I, given by the formula;
For the second choice, we have;
The simple interest, I, given by the formula;
The difference, D, in the amount of interest she would have to pay for the two loans is therefore;
D = I₂ - I₁ = $3,000 - $1,600 = $1,400
The difference in the amount of interest she would have to pay for the two loans = D = $1,400.
For this case we have the following inequality:
The first thing we must do is to graph the linear function:
Then, we must evaluate ordered pairs in the following way:
(x, y)
The ordered pairs that meet the inequality, will be included as part of the graph.
Therefore, the shaded region contains all the ordered pairs that meet the inequality.
