Answer:
P(c) = 0.75c - 9.96
Step-by-step explanation:
In the function p(c), the value that multiplies the variable c (number of cups of lemonade sold) is the increase in the profit for each increase in the number of cups sold, that is, it is the price of each cup of lemonade.
Initially the price of a cup of lemonade is 0.5, and then she increased the price by 25 cents, that is, by 0.25, so the new price is 0.75 (75 cents).
Then, the new function for her profit would be:
P(c) = 0.75c - 9.96
