Answer:
<h2>4 students</h2>
Step-by-step explanation:
Step one:
given
we are told that the total number of students is =16
so 25% of these students preferred pizza
Firstly, we want to know what 25% of 16 will be
so
=25/100*16
=0.25*16
=4
<em>This means that only 4 students preferred pizza</em>

Answer:
6 children
Step-by-step explanation:
If all of the group were adults, the total cost of tickets would be 8×$10 = $80. The actual cost was $80 -62 = $18 less than that. Since each children's ticket saves $3 off the cost of an adult ticket, there were $18/$3 = 6 children's tickets.
There were 6 children in the group.
_____
If you want an equation, you can let c represent the number of children. Then the cost of tickets is ...
8(10 -c) +5c = 62 . . . . 10-c is the number of adults
-3c = -18 . . . . . . . subtract 80
c = -18/-3 = 6 . . . divide by 3
