[Question]Marites internet speed is 10 megabits per second and her monthly internet bill is $20. Marites is planning to upgrade her service and choosing between 20 Mbps and 30 Mbps. If the price of the 30 Mbps is twice the amount of her current monthly bill and the price of the 20 Mbps is $10 more than her current monthly bill, how much will she save per year if she chooses the 20 Mbps than 30 Mbps?
[Answer]The total monthly bill for 30 Mbps is $20 x 2 = $40. She will have to pay $40 x 12 = $480 every year for 30mbps. The total monthly bill for 20 Mbps is $20 + $10 = $30. So, she will have to pay $30 x 12 = $360 for 20 Mbps per year. Therefore the amount she will save per year if she chooses the 20mbps is $480 - $360 = $120. The answer is 120.

Question: The gauge on a water tank shows that the tank is 1/3 full of water. To fill the tank, 16 gallons of water are added. How many gallons of water does the tank hold when full?
Answer:
Given that the tank is 1 / 3 full of water, and that it requires 16 gallons to fill. 1 full tank - 1 / 3 tank = 2 / 3 of the tank is empty, which is equal to 16 gallons. If 2 / 3 of the tank equals 16 gallons, this means 1 / 3 of the tank is equal to 16 / 2 gallons = 8 gallons. The total capacity of the tank or how much the tanks holds = 16 + 8 = 24 gallons. The answer is 24.
