Awoodworker makes wooden checkerboards. her profit is a function of the
price she charges. this graph shows her total profits, y, based on the sales
price, x, of each checkerboard.
identify any zeros of the function, and interpret what the zeros mean in terms
of the situation.

o
a. zero: x= 35. this is the selling price that will give her the greatest
profit.
o
b. zeros: x = 10 and x 60. these are the prices at which she makes
the least and greatest amounts of profit.
o
c. zero: y = 1250. this is the maximum amount of profit she can
make.
o
d. zeros: x= 10 and x = 60. these are the prices at which she neither
makes nor loses money.

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan. (give the answer in billions rounded to the nearest hundredth) b) how does this compare to the actual value for k-12 expenditures in illinois? (lower, higher, same? )
