The attendance at a football game was 400 people. Lower deck seats sold for $15 and upper deck seats sold for $10. Total ticket sales were $4650. How many of each type of ticket were sold? Go Packers!!

Total Attendance= 400

Lower Deck= $15x

Upper Deck= $10y

Total Sold= $4650

15x+10y = 4650

x+y =400

x= 400-y

15(400 - y)+ 10y= 4650

6000-15y+10= 4650

-5y= 4650-6000

y= 1350/5

=270

Lower Deck= 400-270= 130

Upper Deck= 270

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
