Final answer:
The equation for finding the opening bid of a set of wheels that sold for $1,120, which is $20 more than four times the opening bid, is solved by simple algebra. The answer calculated is $275, but since this is not one of the provided options, there appears to be a discrepancy that needs clarification.
Step-by-step explanation:
The student's question revolves around algebra and problem-solving within mathematics. They are trying to find the opening bid of a set of wheels that sold for $1,120, which is $20 more than four times the opening bid. Let's denote the opening bid as 'x'. The equation based on the given information is:
4x + $20 = $1,120
To find the value of x, we need to solve for x:
- Subtract $20 from both sides of the equation: 4x = $1,120 - $20
- 4x = $1,100
- Divide both sides by 4 to find x: x = $1,100 / 4
- x = $275
However, since $275 is not one of the options provided, this indicates the question may contain an error, or we have misinterpreted the provided instructions. As this cannot give us a definitive answer from the options given (a.$250, b.$260, c.$270, d.$280), check the problem statement again or reach out for clarification before selecting an option.
