First, we divide the amount of tip which is $16 by the amount that is used to pay the food bill which is $80. Then, multiply the quotient by 100%. Mathematically,
($16 / $80) x 100% = 20%
Thus, you left 20% of the food bill for the tip.
EF and FG are equal so EF would be 6.1
6.1+6.1=12.2
EG=12.2

Step-by-step explanation:
Answer:
General admissions sold: 880
Reserved seating sold: 256
Step-by-step explanation:
Set up equation:
Variable x = people who bought general admission
Variable y = people who bought reserved seating
x + y = 1136
5x + 7y = 6192
Isolate a variable in any equation:
Y = 1136 - x
Substitute the value of the variable in the other equation:
5x + 7(1136 - x) = 6192
5x + 7952 - 7x = 6192
-2x + 7952 = 6192
-2x = -1760
x = 880
Substitute the value of x in any equation:
880 + y = 1136
y = 256
Check your work:
880 + 256 = 1136
1136 = 1136
Correct!
5(880) + 7(256) = 6192
4400 + 1792 = 6192
6192 = 6192
Correct!
