A: After the first 6 miles, he rowed 15 miles more, reaching 6 + 15 = 21 miles. After resting, he adds 18 miles more, which is 18 + 21 = 39 miles. The answer is 39.

[Question]Nina made a two-layer cake and a dozen cupcakes for her friend's birthday party. Each layer of cake takes the same amount of sugar to make as a dozen cupcakes. Nina used 720 grams of sugar to bake everything. How many grams of sugar are in one cupcake?
[Answer]Nina made 2 cake layers which were equal to 2 x 12 = 24 cupcakes. She made the equivalent of 24 + 12 = 36 cupcakes in all. Thus, there are 720 / 36 = 20 grams of sugar in a cupcake. The answer is 20.
Q: Tonya has $150.00 on her credit card. If she leaves any balance on her card at the end of the month, she is charged 20% interest. If she makes a $50.00 payment on her card, what will be the new balance?
A: Her card has a $150.00 balance and she makes a $50.00 payment so the new balance is 150 - 50 = $100.00. She didn't pay it off so she is charged 20% interest on her $100.00 balance so the interest is .20 * 100 = $20.00. Her balance was $100.00 and she was charged $20.00 in interest so her new balance is 100 + 20 = $120.00. The answer is 120.

Q: Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children's discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets?
A:
The tickets for both of her brothers will cost her $10 * 2 = $20. To buy tickets for all of them, it will cost Isabelle $20 + $20 = $40. Between all of them, they have saved a total of $5 + $5 = $10. Since they have already saved $10, she needs to earn an additional $40 - $10 = $30 to afford the tickets. Since she makes $3 per week, it will take her $30 / ($3 / week) = 10 weeks to save enough money for all of the tickets. The answer is 10.
