I think it’s D. All of the above
Answer:
Marginal cost, average variable cost, and average total cost will increase. Average fixed cost will not change.
Explanation:
Marginal Cost is the change in total cost as a result of producing one extra unit of output.
Variable cost is cost that varies with output level. Average variable cost = variable cost / quantity produced
Fixed cost is cost that doesn't vary with the level of output produced. Average fixed cost = Fixed cost / quantity produced.
Total cost is the sum of fixed and variable cost. average total cost is total cost / quantity produced.
If the price of supplies increase, the cost of production increases and average total cost, average variable cost and marginal cost would increase.
Fixed cost would remain the same.
I hope my answer helps you
The availability of many substitutes increases the elasticity of demand for a good. With the presence of substitutes the consumer has more options to seek out if there are price changes, therefore, the consumer is highly responsive to price changes and thus the elasticity of the demand curve is higher if there are many substitutes.
