Respuesta :
The total money raised by Mr. McDonald's students is $ 6000.
Further Explanation
Given:
Each student sold 16 raffles
Cost/raffle = $ 15
Number of students = 25 students (additional information)
Total money raised?
First step, we are going to calculate how much money each student raised:
[tex]= \boxed {16 \times15\ }[/tex]
This multiplication can be solved using the area model as below:
[tex]= \boxed {16 \times15\ }\\ = \boxed {(6+10) \times (5+10)\ }\\ = \boxed {(6 \times5) + (5 \times10) + (6 \times10) + (10 \times10)\ }\\ = \boxed {30+50+60+100\ }\\ = \boxed {240\ }[/tex]
So, each student will raised $240
If there are 25 students, the total money raised will be:
[tex]= \boxed {25 \times240\ }\\= \boxed {(5+20) \times(40+200)}\\ = \boxed {(5 \times40) + (20 \times40) + (5 \times200) + (20 \times200)\ }\\ = \boxed {200+80+1000+4000\ }\\ = \boxed {6000\ }[/tex]
So, the total money raised by Mr. McDonald's students is $6000
