Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.

Answer:209ft
Step-by-step explanation:
We let y be the unknown value, which is length of conduit.
200^2 + 60^2=y^2
40000 + 3600=y^2
43600=y^2
Square both side
y= sqrt(43600)
y= 208.8061 ft
y=209 ft
