Answer:
B. SS50-SS100-SS50-SS200
Step-by-step explanation:
The total monthly demand is 14,400 toys.
The demand for the Sudsy Soaker 50 is 7,200 which represents 50% of the total monthly demand. This means that, in order to keep a smooth production line, one in every two products assembled must be a Sudsy Soaker 50.
Sudsy Soaker 100, and Sudsy Soaker 200 both have a demand of 3,600 each which corresponds to 25% of the total demand. Thus, one in every four products assembled must be a Sudsy Soaker 100 and one in every four must be a Sudsy Soaker 200.
The only answer choice that fulfills those requirements is alternative B. SS50-SS100-SS50-SS200.
