The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
4) 1081 - 1150 = -69
-69/1150 = -0.06
-0.06 x 100 = -6% = 6% error
Correct answer is letter C.

Answer:
ticket cost = 37.23
Equation:- $930.75 = 25F
Step-by-step explanation:
$930.75 = 25F
F being the variable, representing the ticket cost
The total amount is equal to the number of seat per ticket
Part B:- 930.75/ 25 = 25F/25
F= 37.23
Therefore the ticket cost 37.23 for each ticket because they all cost the same
