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]Jesse received $50 as a gift to buy what she wants. She goes to the mall and falls in love with a novel that costs her $7. Then she went to lunch because she was very hungry and spent twice as much as the novel cost her. How much money did Jesse have left after going to the mall?
[Answer]Jesse bought a novel for $7. She then bought lunch for twice the value of the novel, so lunch cost her $7 x 2 = $14. To find out how much money she has left from her gift she must know the total amount she spent $7 + $14 = $21. Her gift was $50, so she was left with $50 - $21 = $29. The answer is 29.
Q: A luxury perfume costs $1200. The store owner decided to increase its price by 10% so that he could earn more profit. Few weeks had past but the perfume was still not sold. So, the owner decided to lower the price by 15%. By how much was the final price lower than the original price?
A: There was a $1200 x 10 / 100 = $120 increase of the original price. So, the perfume was priced for $1200 + $120 = $1320. Then, 15% of the new price is $1320 x 15 / 100 = $198. So, the final price is now $1320 - $198 = $1122. Therefore, the final price is $1200 - $1122 = $78 lower than the original price. The answer is 78.

Paul has 10 hours of homework from weekdays because 2 x 5 = 10. He has 15 total hours because 5 + 10 = 15. He has 5 days to do his homework because 7 - 2 = 5. He needs to do 3 hours a night because 15 / 5 = 3. The answer is 3.
