Answer
(a) 881 lb
(b) 15 lb/day/steer
Work Step by Step
(a) To get the average, we sum the weights and divide by 8:
Average weight=$\frac{(856 + 754 + 1044 + 928 + 888 + 734 + 953 + 891)}{8}=881$ pounds
(b) We divide the number of pounds of feed by the number of days:
$\frac{4320 \mathrm{\ lb}}{36 \mathrm{\ days}}=120$ lb/day
Next we divide this average daily feed consumption by the number of steers:
$\frac{120 \mathrm{\ lb/day}}{8 \mathrm{\ steers}}=15$ lb/day/steer
