Answer:
P(c) = 0.75c - 9.96
Explanations:
The profit made by Emma by selling c cups of Lemonades is given by the function:
P(c) = 0.50c - 9.96
Note that:
Profit = Selling Price - Cost Price
Therefore from P(c) = 0.50c - 9.96:
Selling price = 0.50c, meaning that he sold 1 cup for $0.50
Cost price = $9.96
She raised the price for this weekend by 25 cents ($0.25) per cup :
That means she now sells a cup at ($0.50+$0.25) = $0.75
The selling price for c cups = $0.75
Therefore, her profit for this weekend will be:
P(c) = 0.75c - 9.96
