The total cost for 5 pairs of jeans after the discount is 250 dollars.

Step by step solution

01

Problem Development

Let's devise the following problem: 'A local clothing store holds a sale wherein every item costs 20 dollars off the original price. If a pair of jeans originally cost 70 dollars, how much would 5 pairs of the jeans cost, after discount?' This problem can be solved by using a linear equation.
02

Formulate the Linear Equation

The problem can be represented by a linear equation. The original price for the jeans is 70 dollars. After the discount is applied, each pair cost 70 - 20 = 50 dollars. If one buys 5 pairs, the total cost would be represented by the equation \( C = 50 * n \), where \( C \) is the total cost and \( n \) is the number of jeans bought.
03

Solve the Linear Equation

Substituting \( n = 5 \) into the equation \( C = 50 * n \), we get \( C = 50 * 5 = 250 \). Hence, the total cost for 5 pairs of jeans, after the discount, is 250 dollars.

On two examinations, you have grades of 86 and 88 . There is an optional final examination, which counts as one grade. You decide to take the final in order to get a course grade of \(\mathrm{A}\), meaning a final average of at least 90 . a. What must you get on the final to earn an A in the course? b. By taking the final, if you do poorly, you might risk the \(B\) that you have in the course based on the first two exam grades. If your final average is less than \(80,\) you will lose your \(B\) in the course. Describe the grades on the final that will cause this to happen.
