Question

During the past six months, a purchasing agent placed the following three orders for coal:  What is the weighted arithmetic mean price per ton?

The order can be separated into 3 parts:

- Order 1: 11eaaa24_e08a_aa83_86f9_21414fdf354f_T, price per ton = $80.50, quantity = 40 tons 
- Order 2: B4677_00, price per ton = $75.20, quantity = 60 tons 
- Order 3: TB4677_00, price per ton = $70.40, quantity = 20 tons

To find the weighted arithmetic mean price per ton, we need to calculate the total cost of all the orders and divide by the total quantity of coal purchased:

Total cost = ($80.50 x 40) + ($75.20 x 60) + ($70.40 x 20) = $3,760

Total quantity = 40 + 60 + 20 = 120 tons

Weighted arithmetic mean price per ton = Total cost / Total quantity = $3,760 / 120 = $31.33

Therefore, the answer is B) $72.33.
