Final answer:
Without additional information regarding the discount percentage or amount, it is not possible to calculate the original price of the easel that Lara bought for $23.
Step-by-step explanation:
The question asks to determine the original price of an easel that Lara bought on sale for $23. To solve this problem, we would need more information, such as the discount percentage or the exact amount of discount given during the sale. Without this additional information, it is not possible to calculate the original price accurately. In a typical mathematical problem like this, the equation to find the original price would be the sale price divided by (1 minus the discount rate).
However, since the necessary details are not provided, we can only say that to find the original price, we would need the percentage of the sale or the amount of discount that was applied to the original price. This is a common type of math problem in discount and percentage calculations, often taught in middle school mathematics.
