He needs 4 boxes :)
Dozen= 12
48 ÷12=4
The answer is C. x=4
Explanation) 49 - 7 (4) = 21
7 (4) = 28
49 - 28 = 21
X - number of the adults, y - number of children;
The system is:
10 x + 6 y = 3292
x + y = 350 => y = 350 - x
----------------------
10 x + 6 * ( 350 - x ) = 3292
10 x + 2100 - 6 x = 3292
4 x = 3292 - 2100
4 x = 1192
x = 1192 : 4
x = 298
y = 350 - 298
y = 52
