Final answer:
To determine the original price of the jeans, the equation ⅗ j - 20 = 9.64 is solved by adding $20 to both sides, multiplying by 5/3, and calculating the result to find that the original price was $49.40.
Step-by-step explanation:
To find the original price of the jeans that Shane purchased, we need to solve the equation ⅗ j - 20 = 9.64 for j, where j represents the original price. Here are the steps to calculate it:
- Add $20 to both sides of the equation to isolate the term with j: ⅗ j = 9.64 + 20.
- Combine the numbers on the right side of the equation: ⅗ j = 29.64.
- Multiply both sides of the equation by 5/3 to solve for j: j = (29.64) * (5/3).
- Calculate the value of j: j = 49.40.
Therefore, the original price of the jeans that Shane purchased was $49.40.
