Answer:
The correct answer is B.
Explanation:
Giving the following information:
Investment= $600 today and $600 at the end of year 5
Interest rate= 3%
To calculate the final value, we need to apply the following formula on each investment:
FV= PV*(1+i)^n
FV= 600*(1.03^6)= $716.43
FV= 600*(1.03^1)= $618
Total FV= $1,334.43
Answer:
57.8$
Explanation:
Here we know that:
- One trip to work averages 14 miles
- Therefore, one return trip home-work averages 14*2=28 miles
- You work 20 days per month
So, the average number of miles per month is:

Then, we also know that the car averages 28 miles per gallon; this means that the number of gallons consumed on average in 1 month is equal to the average number of miles (560) divided by 28:

So, 20 gallons per month.
Finally, we know that the cost of the gas is 2.89$/gallon. Therefore, the average total cost per month is equal to the average number of gallons per month (20) times the cost per gallon:
