Answer:
$7.30
Step-by-step explanation:
The problem statement gives rise to two equations:
- 3a +2c = 33.50
- 1a +4c = 30.50
If we double the first equation and subtract the second, we have ...
2(3a +2c) -(1a +4c) = 2(33.50) -(30.50)
5a = 36.50 . . . . simplify
a = 7.30 . . . . . . .divide by 5
The cost of one adult ticket is $7.30.
4 times the sum of the least and greatest integers ⇒ 4(n + n +2) = 4n + 8
12 less than three times the least integer ⇒ 3n - 12
4n + 8 = 3n - 12
4n - 3n + 8 = 3n - 3n - 12
n + 8 - 8 = -12 - 8
n = -20
-20, -19, -18 are the integers and the least is -20
