Jenny is planning her catering budget for her wedding. She's going to have 80 guests. 3 times as many guests want steak as chicken. If each steak entree costs $25 and each chicken entree costs $18, how much is the total catering budget?
Let's think: Let s be the number of guests who want steak and c be the number who want chicken. We know that s + c = 80 and s = 3c. Substituting the second equation into the first equation, we get 3c + c = 80. Combining like terms, we get 4c = 80. Dividing both sides by 4, we get c = 20. Then multiply the number of guests who want chicken by the cost of each chicken entree: 20 guests * $18 / guest = $360. Then triple the number of guests who want chicken to find the number who want steak: 20 guests * 3 = 60 guests. Then multiply the number of guests who want steak by the cost of each steak entree: 60 guests * $25 / guest = $1500. Then add the cost of the steak and chicken entrees to find the total cost: $1500 + $360 = $1860.. The answer is: 1860.

To get to an island called "Virgo", Tom needs to travel by plane and then by boat. The plane trip is four times longer than the boat trip, and the boat trip takes up to 2 hours. In how many hours is Tom able to get to the "Virgo" island?
Let's think: The plane trip is four times longer than the 2 - hour long boat trip, which means it takes 4 * 2 = 8 hours. So in total, the whole journey to "Virgo" islands lasts 8 + 2 = 10 hours.. The answer is: 10.

Forty percent of the students have elected to learn from home during the pandemic. The remaining students are divided into two equal groups, only one of which is physically in school on any day. What percent of students are present in school?
Let's think: 100 - 40 = 60 percent of students are remaining. 60 / 2 = 30 percent are present in school.. The answer is: 30.

Madeline spends 18 hours a week in class. She spends 4 hours per day working on homework. She spends 8 hours per day sleeping. She works part-time 20 hours per week. How many hours left over does Madeline have?
Let's think:
Madeline spends 4 * 7 = 28 hours on homework. She spends 8 * 7 - 56 hours sleeping. Therefore, she is busy 28 + 18 + 56 + 20 = 122 hours per week. There are 7 * 24 = 168 hours per week. Thus, Madeline has 168 - 122 = 46 hours left over.. The answer is: 46.
