Final answer:
To find the change in stock value over three days, subtract the initial value from the final value.
Step-by-step explanation:
To find the change in stock value over three days, we need to calculate the difference between the initial value and the final value. Let's say the initial value on Monday is 'x'. On Monday, the value of the stock decreased by 'wyndham' points, so the value on Tuesday will be 'x - wyndham'. On Tuesday, the value increased by 3 3/4 points, so the value on Wednesday will be '(x - wyndham) + 3 3/4'. To find the change in stock value, we subtract the initial value from the final value: '(x - wyndham) + 3 3/4 - x'. Simplifying this expression will give us the change in stock value over three days.
