PLEASE HURRY!!!!

Answer 1

Answer: The mean weekly allowance is 3.5 dollars

Step-by-step explanation:

Given: Number of students receive no amount =7

Number of students receive $3=5

Then, total amount 5 students receive = $5\times3=\ 15$

Number of students receive $5=7

Then, total amount 7 students receive = $5\times7=\ 35$

Number of students receive $6=3

Then, total amount 3 students receive = $6\times3=\ 18$

Number of students receive $8=2

Then, total amount 2 students receive = $2\times8=\ 16$

Now, the total amount all students receive=$15+35+18+16=84$

The total students = $7+5+7+3+2=24$

Now, Mean=$\frac{\text{Total amount}}{\text{Total students}}=\frac{84}{24}=\ 3.5$

Hence, The mean weekly allowance is 3.5 dollars.

Answer 2

The mean weekly allowance is 3.50 dollars.
