14. mrs. rockwell lost money on an investment at a rate of $4 per day. what is the change in her investment, due to the lost money, after 4 weeks? (example 2)
Answer
Explanation:
Step1: Calculate number of days in 4 weeks
Since 1 week has 7 days, for 4 weeks, the number of days $d = 4\times7=28$ days.
Step2: Calculate total loss
The loss per day is $4. So the total loss $L$ after 28 days is $L = 4\times d$. Substituting $d = 28$ into the formula, we get $L=4\times28 = 112$. Since it is a loss, the change in investment is - 112.
Answer:
- 112
