Final answer:
The question introduces basic principles of pricing models featuring a flat fee and a variable cost, applicable to a high school-level mathematics problem on linear equations representing real-world situations.
Step-by-step explanation:
The question deals with understanding how a company charges for a service or product, in this case, frozen yoghurt. The company has a pricing model which includes a flat fee and a variable cost based on the amount of product consumed. Specifically, the frozen yoghurt company charges a flat fee of $1.00 and an additional $0.30 per ounce of frozen yoghurt. To represent this mathematically, one can use the equation C = 1 + 0.30n, where C represents the total cost and n represents the number of ounces. The given examples with the price of frozen raspberries doubling to $8 per pack and the coffee shop changing its pricing model illustrate different ways that pricing structures can impact a consumer's cost.
