Answer:
12s + 5c = 125
5s + 5c = 85
price of senior citizen ticket = $5.71
price of a child's ticket = $11.29
Step-by-step explanation:
This question can be solved using simultaneous equation
12s + 5c = 125 equation 1
5s + 5c = 85 equation 2
subtract equation 1 from 1
7s == 40
s = 40/7 = 5.71
Substitute for s in equation 1
12(5.71) + 5c = 125
68.57 + 5c = 125
5c = 125 - 68.57
5c = 56.43
c =11.29
21n + 7
Combine like terms.
n, 7n, 7n, 3n, and 3n are all like terms. These can be added together as 21n.
7 is the only term by itself.
Put these together to get 21n + 7.

Answer:
there are 380 seats in total
Step-by-step explanation:
286 + 18 = 304 which is four-fifths of the seat. since 304 seats is 80% of the total seats then if you divide it by 80 then multiply it by 100 you get 380.
so one fifth would be 76 seats and if you multiply it by 4 you get 304 which is four fifths of the seat.
