Friday Saturday Totals
7th graders 24 x y
8th graders a 35 b
Totals c d 52
To find the total number of eighth graders, we can use the fact that the total number of eighth graders should be the sum of the number of eighth graders on Friday and Saturday. Thus:
a + b = 35
And, based on the totals:
a + x = c
b + y = d
x + y = 52
To find the value of a and b, we solve the system of equations by substituting:
a + b = 35
a + x = c
b = c - x
Then:
a + c - x = 35
a = 35 - c + x
x + y = 52
x = 52 - y
Now substitute x in terms of c back into the equation a = 35 - c + x:
a = 35 - c + 52 - y
Thus, a = 87 - c - y
Now substitute a back into the equation for b in terms of c:
b = c - x
b = c - 52 + y
Now, sum a and b:
87 - c - y + c - 52 + y = 35
35 = 35
This equation is true for any values of c and y, confirming that the total number of eighth graders is 35.
7th graders 24 x y
8th graders a 35 b
Totals c d 52
To find the total number of eighth graders, we can use the fact that the total number of eighth graders should be the sum of the number of eighth graders on Friday and Saturday. Thus:
a + b = 35
And, based on the totals:
a + x = c
b + y = d
x + y = 52
To find the value of a and b, we solve the system of equations by substituting:
a + b = 35
a + x = c
b = c - x
Then:
a + c - x = 35
a = 35 - c + x
x + y = 52
x = 52 - y
Now substitute x in terms of c back into the equation a = 35 - c + x:
a = 35 - c + 52 - y
Thus, a = 87 - c - y
Now substitute a back into the equation for b in terms of c:
b = c - x
b = c - 52 + y
Now, sum a and b:
87 - c - y + c - 52 + y = 35
35 = 35
This equation is true for any values of c and y, confirming that the total number of eighth graders is 35.

To determine the total number of people who like tacos, we'll complete the table with the given values:
Pizza Tacos Chicken Totals
7th graders 24 a b 120
8th graders c 35 46 d
Totals e f g 191
Let's use the information in the table to fill in the missing values:
- From the row totals:
a + b = 120
c + 35 + 46 = 81
d = 71
- From the column totals:
a + c = 52
b + 35 = 91
g = 191
Solving the system of equations, we find:
a = 15
b = 76
c = 37
d = 71
The total number of people who like tacos is 76.
