1. x+y=86
y=86-x
97x+123(86-x)=9304
97x+10578-123x=9304
-26x=-1274
(((-26x/26=-1274/-26}}}
x=49, 86-49 = 37 About 49 $97 tickects were purchased and 37 $123 dollar tickets were purchased
--------------------------------------------------------------------------
2. Let the burgers be x and soft drinks be y
7x+5y=10.08
y=2.016-1.4x
8x+6y=12.28
8x+6(2.012.016-1.4x)=12.28
8x+12.096-8.4x=12.28
-0.4x=-0.184
x=0.46
Sub in: y=2.016-1.4(0.46)/// y=1.37
Hence the burger costs $1.37 and the soft crink costs $0.46
---------------------------------------------------------------------------
3.Let the one point shot be x and the 2 point shot be y
x=y=27
y=27-x
x+2(27-x)=35
x+54-2x=35
-x=-19
x=19
y=27-(19)
y=8
Hence he scored 19 one pointers and 8 2 pointers
