Answer:
45 premium tickets were sold
Step-by-step explanation:
p = premium
d = deluxe
r = regular
p+d+r = 273
6p+4d + 2r = 836
118+d = r
Replace r with 118+d
p+d+118+d = 273
p +2d = 273-118
p+2d = 155
6p+4d + 2(118+d) = 836
6p+4d + 236+2d = 836
6p +6d = 836-236
6p + 6d = 600
Divide by 6
p+d = 100
d = 100-p
Replace d in p +2d= 155
p +2(100-p) = 155
p+200-2p = 155
-p = 155-200
-p =-45
p =45

Answer:
A: P = 41100 - 590t
B: 34610
Step-by-step explanation:
equation = 41100-(41100-36380)/(2011-2003)t
plug it in
41100 - 590(2014-2003)=34610
 
        
             
        
        
        
It will take 7/8 of a minute because you just multiply 1/8 by 7
