Answer 1

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
