Answer

The ending price was $45.

Work Step by Step

If the price per share of a stock changes by -4.50, this means it is decreasing by 4.50. Because this goes on for 5 consecutive days, multiply 5 by 4.50 which comes out to 22.50. Finally, to find the end price, subtract the change in price per share of a stock over 5 consecutive days from the starting price (67.50) which is equivalent to $45.00.
