The restrictions are:
1) x ≥ 0
2) number of lower bowl seats = 65% * 18500 = 12,025
=> x ≤ 12,025
3) y ≥ 0
4) number of upper bowl seats = 35% * 18500 = 6,475
=> y ≤ 6,475
It is not necessary to state that x + y ≤ 18,500 because it is included in the other restrictions.
EXPLANATION
Given the equation:
a+23 = 38
Adding -23 to both sides will give us:
a= 38-23
a=15
Answer--> B. 15 because to isolate a, you would subtract 23 from 38.
