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? Give me reasons, before answering the question
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. So the final answer is 120.
