goes down \( 40 \frac{1}{2} \) points and stays at this level for most of the day. At the end of the day the stock market goes up \( 90 \frac{3}{4} \) points from the low at dek maket trom the beginning of the day to the end of the day?

The market first goes down 40 1/2 points, then later rises 90 3/4 points from that low point. To find the overall change from the start of the day to the end of the day, subtract the drop from the rise. Step 1: Convert the mixed numbers to decimals (if preferred): • 40 1/2 = 40.5 • 90 3/4 = 90.75 Step 2: Compute the overall change by adding the rise to the recovery of the drop:   Overall change = 90.75 − 40.5 = 50.25 points Thus, from the beginning of the day to the end of the day, the stock market increased by 50 1/4 points (or 50.25 points).
