She brings 3 donuts because a dozen is 12 and 1/4 of 12 is 3.
Answer:
Step-by-step explanation:
a+s=14
a=14-s
a+8s=56, using a from above in this equation gives
14-s+8s=56
14+7s=56
7s=42
s=6
a=14-s
a=14-6=8
So student tickets cost $6 and adult tickets cost $8.
There will be 42 in each row with 2 left over
