Mrs. Rockwell lost money on an investment at a rate of $4 per day. What integer represents the change in her investment, due to the lost money, after 4 weeks?

-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.
