Answer:
The first plan of $49 will be best plan for her.
Step-by-step explanation:
Katherine used 1479 minutes call in the last 6 months.
So, the average monthly call that Katherine made is
minutes.
Now, there are two plans for mobile recharge.
One is 250 minutes call time for $49 and the other is 350 minutes call time for $65.
Since 246.5 < 250 and Katherine does not want to spend more for minutes she won't use, then the first plan of $49 will be the best plan for her. (Answer)
The actual answer is 154 but the closest estimate would be 150.
Just multiply the number of gallons filled her gas tank (14) and how many time she filled it (11).
Amount of money invested: P=$4,100
Interest rate percentage in decimal form: r=7.25%=7.25/100→r=0.0725
Time in years: t=8
Total money in the account at time t: A=?
A=Pe^(rt)
A=$4,100e^(0.0725*8)
A=$4,100e^0.58
A=$4,100(1.786038431)
A=$7,322.757566
A=$7,322.76
Answer: The balance in the account after 8 years is $7,322.76
