8 0

Answer:

95

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = \frac{83+81+73+x}{4} = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95

Answer:

$75

Step-by-step explanation:

<h3>Steps to determining the answer</h3>
  1. Determine the number of students that would pay in the second week. This can be known by subtracting 14 from 20. 20 is the total number of students. 14 is the number of students that paid in the first week.
  2. Multiply the answer gotten from one above by the price of the ticket

20 - 14 = 6

6 students would pay in the second week

6 x $12.50 = $75
