3. connor is making squares out of toothpicks. each square is formed from 4 toothpicks. if he has 13 toothpicks, how many squares can he build?

Explanation:

Step1: Deduct adult admission cost

Remaining money: $40 - 10 = 30$

Step2: Calculate total children allowed

Total children: $\frac{30}{4} = 7.5$, round down to 7

Step3: Subtract Kristen to get friends

Friends: $7 - 1 = 6$

Step4: Define student-guest ratio

1 student + 2 guests = 3 people per student group

Step5: Calculate number of students

Students: $\frac{45}{3} = 15$

Step6: Count full squares from toothpicks

Squares: $\frac{13}{4} = 3.25$, round down to 3

Answer:

1. 6
2. 15
3. 3
