In the city park, there are various attractions for kids and their parents. The entrance ticket to the park is $5, but for each attraction, you have to pay separately - such ticket costs $2 for kids and $4 for parents. How much would a family with 4 children, their parents, and her grandmother pay for visiting the park, and one attraction inside? Give me reasons, before answering the question
The whole family consists of 4 + 2 + 1 = 7 persons. The entrance ticket to the park costs the same for every person, so the family would need to pay 7 * 5 = $35 to enter. For visiting the attraction the tickets would cost 4 * 2 = $8 for the kids. Their parents and grandmother would need to pay 3 * 4 = $12. That means a total cost for the family standing at 35 + 8 + 12 = $55. So the final answer is 55.
