Q: It's Yvette's turn to treat herself and her three best friends to a round of ice cream sundaes. Alicia orders the peanut butter sundae for $7.50. Brant orders the Royal banana split sundae for $10.00. Josh orders the death by chocolate sundae for $8.50 and Yvette orders the cherry jubilee sundae for $9.00. She leaves her waiter a 20% tip. How much will her final bill be?
A: Yvette spent 7.50 + 10 + 8.5 + 9 = $35.00 on ice cream sundaes. Her bill comes to $35.00 and she leaves a 20% tip for the waiter so that's 35 * .20 = $7.00. The bill was $35.00 and she added a $7.00 tip for a total of 35 + 7 = $42.00. The answer is 42.

[Question]Carolyn practices the piano for 20 minutes a day and the violin for three times as long. If she practice six days a week, how many minutes does she spend practicing in a month with four weeks?
[Answer]First find Carolyn's total violin practice time by tripling her piano practice time: 20 minutes / day * 3 = 60 minutes / day. Then find the total amount of time she spends practicing each day: 60 minutes / day + 20 minutes / day = 80 minutes / day. Then find the total time she spends practicing each week: 80 minutes / day * 6 days / week = 480 minutes / week. Then find the total time she spends practicing each month: 480 minutes / week * 4 weeks / month = 1920 minutes / month. The answer is 1920.
[Question]A taco truck is selling soft tacos for $2 and hard shell tacos for $5 during the lunch rush. The first group of customers is a family that buys four hard shell tacos and three soft tacos. The rest of the customers in the lunch rush only buy two soft tacos each. There were ten customers after the family. How many dollars did the taco truck make during the lunch rush?
[Answer]
The taco truck sold 3 + 2 * 10 = 3 + 20 = 23 soft tacos. It made 2 * 23 = $46 from soft tacos. It made 5 * 4 = $20 from hard shell tacos. Thus, the taco truck made 46 + 20 = $66 during the lunch rush. The answer is 66.
