Chair P, from Design Solutions, cost $60 per chair. Chair Q, from Seat Unlimited, costs $90 per chair. An office manager often has to buy several chairs to stock the floor space of new offices. On one occasion, she orders p of chair P, and q of chair Q. The average cost of a chair would be
average = \frac{60p + 90q}{p + q}
In the table, select a value for p and a value for q corresponding to an average cost per chair of $70. Make only two selections, one in each column.
