Answer with step-by-step thinking: There are 1 + 3 = 4 of them who will go to the park. The ticket and a set of snack cost $18 + $5 = $23. So, it will cost Jerimee and her 3 friends $23 x 4 = $92.
So the answer is 92.


Question: Cathy and Chris got summer jobs at the cake shop and were supposed to work 20 hours per week each for 2 months. During that time, Chris got sick for one week and Cathy took her shifts. If there are four weeks in a month, how many hours did Cathy work during the 2 months?
Answer with step-by-step thinking: There are 4 weeks in a month so Cathy and Chris were supposed to work for 4 weeks / month x 2 months = 8 weeks each. Since Chris got sick then Chris was only able to work for 8 weeks - 1 week = 7 weeks while Cathy worked for 8 weeks + 1 week = 9 weeks. Therefore, Cathy worked for 9 weeks x 20 hours / week = 180 hours.
So the answer is 180.


Question: Chandra is going on a monster hunt. After a big storm, there have been lost monsters all around the castle grounds for the last 5 days. Chandra wants to rope them all up and return them to the swamps where they will be the most comfortable. On the first day she saw 2 monsters near the castle walls. Every day after that she saw double the amount as the day before. After 5 days how many monsters does she need to lead back to the swamps?
Answer with step-by-step thinking:
On the first day Chandra saw 2 monsters and on day 2 she saw twice that amount, 2 x 2 = 4 monsters seen on day 2. On day 3 she saw double that amount of monsters, 4 x 2 = 8. On day 4 she saw double that amount of monsters, 8 x 2 = 16. On day 5 she saw double that amount of monsters, 16 x 2 = 32. Altogether Chandra saw 2 + 4 + 8 + 16 + 32 lost monsters = 62 total lost monsters that Chandra needs to lead back to the swamps.
So the answer is 62.
