They will have an initial cost of $500 to buy equipment and an additional $1.25 cost for each slushie they sell. They plan to charge $3.50 for each slushie. Let C(x) represent the cost (in dollars) associated with
starting and running the business and R(x) represent the revenue (in dollars) earned
from sales. Let × represent the
number of slushies sold
