Answer: -112
Step-by-step explanation:
Given: Rate of lost money on an investment = $4 per day.
Since 1 week = 7 days
So, Amount of money she lost in 1 weeks = $ 4 x 7 = $28
⇒ Amount of money she lost in 4 weeks = $ 28 x 4 = $112
Since in integers, a loss is represented by negative integer.
So, Mrs. Rockwell lost $112 after 4 weeks which is represented by "-112" integers.
