Asmall 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, 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?

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
