Final answer:
Model A has the lowest fixed cost and Model C has the lowest variable cost.
Step-by-step explanation:
Let's analyze each statement to determine which ones are true:
- a) Model A has the lowest fixed cost. We can see from the cost models that Model A has a fixed cost of $8,037. Comparing this to the fixed costs of Models B and C, we can determine that Model A does indeed have the lowest fixed cost.
- b) Model B has the highest fixed cost. Model B has a fixed cost of $13,054. Comparing this to the fixed costs of Models A and C, we can determine that Model B does have the highest fixed cost.
- c) Model C has the lowest variable cost. To determine which model has the lowest variable cost, we need to compare the coefficients of the x term in each cost model. Model A has a coefficient of 1.72, Model B has a coefficient of 2.18, and Model C has a coefficient of 1.89. Therefore, Model C has the lowest variable cost.
- d) Each additional Model B spinner produced will increase the total cost by 2.18%. This statement is not supported by the given information. The coefficient of the x term represents the increase in cost for each additional spinner produced, not the percentage increase.
- e) Each additional Model A spinner produced will increase the total cost by $1.72. This statement is supported by the given information. The coefficient of the x term in Model A represents the increase in cost for each additional spinner produced, which is $1.72.
- f) The fixed costs of models A and C combined are greater than the fixed cost of model B. The fixed costs of Models A and C combined would be $8,037 + $4,088 = $12,125. Comparing this to the fixed cost of Model B, we can determine that the fixed costs of Models A and C combined are indeed greater than the fixed cost of Model B.
Based on this analysis, the two true statements are:
- Model A has the lowest fixed cost.
- Model C has the lowest variable cost.
