Explanation:

Step1: Calculate remaining budget for crepe - paper in question 2

The total budget is $100$. She buys the LifeEyes conversion kit for $49.99$ and 2 strands of orange string - lights at $12.99$ each. The cost of the string - lights is $2\times12.99 = 25.98$. The total amount spent on the kit and string - lights is $49.99+25.98 = 75.97$. The remaining budget for crepe - paper is $100 - 75.97=24.03$.

Step2: Calculate number of crepe - paper rolls

The price of each roll of crepe - paper is $3.49$. The number of rolls of crepe - paper she can buy is $\lfloor\frac{24.03}{3.49}
floor=\lfloor6.8854
floor = 6$.

Step3: Calculate remaining money in question 2

The money spent on crepe - paper is $6\times3.49 = 20.94$. The remaining money is $24.03−20.94 = 3.09$.

Step4: Calculate total budget in question 3A

There are 28 students and each student brings in $5$. The total budget is $28\times5=140$.

Step5: Calculate number of groups in question 3B

There are 28 students and they split into groups of 4. The number of groups is $\frac{28}{4}=7$.

Step6: Calculate total cost of decorations in question 3B

Each group gets 2 pumpkins at $5.26$ each, 2 rolls of orange crepe - paper at $3.49$ each, and 1 roll of black crepe - paper at $3.49$ each.
The cost for each group is $(2\times5.26)+(2\times3.49)+3.49=10.52 + 6.98+3.49 = 21$.
The total cost for all 7 groups is $7\times21 = 147$.

Step7: Answer question 3C

The total budget is $140$ and the total cost is $147$. Since $147>140$, the class will not stick to its budget.

Answer:

1. Number of pumpkins: $\lfloor\frac{250 - 180}{5.26}

floor=\lfloor\frac{70}{5.26}
floor = 13$
2A. Number of crepe - paper rolls: 6
2B. Remaining money: $3.09$
3A. Total budget: $140$
3B. Total cost of decorations: $147$
