A small cafe sells drip coffee for \$0.95 per cup. On average, it costs the cafe \$0.25 to make a cup of coffee (for grounds, hot water, filters). The cafe also has a fixed daily cost of \$200(for rent, wages, and utilities). (a) Let R, C, and P be the cafe's daily revenue, costs, and profit, respectively, for selling x cups of coffee in a day. Find formulas for R, C, and P as functions of x. [Hint: The revenue, R, is the total amount of money that the cafe brings in. the cost, C, includes the fixed daily cost as well as the cost for all x cups of coffee sold. P is the cafe's profit after

costs have been accounted for. (b) Plot P against x. for what x-values is the graph of P below the x-axis? Above the x-axis? Interpret your results. (c) Interpret the slope and both intercepts of your graph in practical terms

I'll start u off, then I think u should sit and think about it a bit, it is not that difficult. R=0.95x (ie x cups of coffee at 0.95)
