Final answer:
Without a graph or specific pricing model, we cannot accurately determine the price Lashayia should charge for 10 brownies. A price per item model would allow us to multiply the cost per brownie by 10 to find the total price, but this cost per brownie is not provided in the information given.
Step-by-step explanation:
To determine how much Lashayia should charge for 10 brownies based on the information provided, we need a graph representing Lashayia's sales or a similar linear equation like the one provided for Svetlana's tutoring sessions. In the tutoring example, Svetlana charges a one-time fee plus an hourly rate. If Lashayia's brownie sales follow a similar linear model where she has a fixed cost and an additional charge per brownie, we could expect an equation in the form of y = fixed cost + (price per brownie × number of brownies).
Unfortunately, the given information does not include enough details to establish Lashayia's exact pricing model for her brownie sales. Without the specific relationship between the number of brownies sold and the total earnings, we cannot calculate the exact price to charge for 10 brownies.
Alternatively, if Lashayia's pricing model is a simple cost per item with no fixed costs, and assuming each brownie is priced the same, you could find the total price for 10 brownies by multiplying the cost per brownie by 10. However, without knowing the cost per brownie, which is not provided, we cannot provide a definitive answer.
