Answer:
number o students bought pennants = 18
number of student bought fancy ones=12
Step-by-step explanation:
Let x be the number o students bought pennants
and y be the number of student bought fancy ones
total 30 students


Plain pennants cost $4 each and fancy ones cost $8 each.

Substitute 30-x for y in second equation



Subtract 240 from both sides

divide both sides by -4
x=18


number o students bought pennants = 18
number of student bought fancy ones=12
362= 300 + 60 + 2
(4×300) + (4×60) + (4×2)
1200 + 240 + 8
1448
