Answer
Explanation:
Step1: Determine number of days in 4 weeks
There are 7 days in a week, so for 4 weeks, the number of days $d = 4\times7=28$ days.
Step2: Calculate total money lost
The rate of money - loss is $4 per day. So the total change in her investment (money lost) $C$ is the rate per day times the number of days. $C = 4\times d$. Substituting $d = 28$ into the formula, we get $C=4\times28 = 112$. Since it is a loss, the integer representing the change is - 112.
Answer:
- 112
