During one week, the price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days. Which integer represents the change in the price of the stock over the week?

A. -20
B. 4
C. 20

Answer 1

To find the overall change in the stock price, calculate the total decrease ($12) and the total increase ($8), then subtract the decrease from the increase to get a result of -$4.

Step-by-step explanation:

The question asks to calculate the overall change in the price of a stock over a week. The stock decreased $4 per day for 3 days and increased $2 per day for 4 days.

1. Calculate the total decrease: $4/day × 3 days = $12.
2. Calculate the total increase: $2/day × 4 days = $8.
3. Determine the overall change: $8 (total increase) - $12 (total decrease) = -$4.

The integer that represents the change in the price of the stock over the week is -4.
