Will mark brainliest for all 4 :)

1. so you have $114
weekdays weekends
18. 21
just divide 114 by 18 and 21
114÷18 = 6.3 which means 6 tickets
and 114÷ 21 = 5.4 which gives us 5 tickets
so the answer is
for weekdays the max ticket number I can get is 6 and for weekends is 5
2. we do the same method as above
for the lawn ( weekdays) seat we get 20 tickets
and for the lower box (weekend) we get 6 tickets max.
3. bleachers weekend seats = 20 tickets
line box weekday seats = 19 tickets
4. both of them can give exactly 7 tickets
