Correct answer: c (51.55)
Explanation:
According to the question,
Total cost of 15 goats and 18 sheep = $1678 .....i
Total average cost of 15 goats = $750 .....ii
ā“ The cost of 1 goat = 750/15 = 50.
Hence, the cost of 1 goat = $50 .....iii
Now, the average cost of 18 sheep = 1678 ā 750 = 928 .....iv
ā“ The average cost of 1 sheep = 928/18 = 51.55
Hence, the average cost of each of the 18 sheep's is $51.55.
Hence, the correct answer is option c.
Thanks.
