Can anyone help me by solving this problem?
Pam bought 15 goats and 18 sheep for a total price of $1678. If the cost of all the 15 goats is $750, find the average cost of 1 sheep.
a. $ 50
b. $ 51
c. $ 51.55
d. $ 55
e. None of the above
Thanks
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
∴ The cost of 1 goat = 750/15 = 50.
Hence, the cost of 1 goat = $50 …..iii
Now, the average cost of 18 sheep = 1678 – 750 = 928 …..iv
∴ 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.
