Answer:

B. $16.13

Step-by-step explanation:

The Total Students= 82+74+96+99=351

Sum of earnings of 82 seniors = $26.75 x 82 = $ 2193.5

Sum of earnings of 74 juniors = $ 12.25 x 74 = $ 906.5

Sum of earnings of 96 sophomores = $15.50 x 96 = $ 1488

Sum of earnings of 99 freshmen= $ 10.85 x 99 = $ 1074.15

Total earnings = $2193.5 + $ 906.5 + $1488 + $ 1074.15 = $ 5662.15

( Total Earnings) ÷ (Total Students)

= $5662.15 ÷ 351

= $16.13
