Concept explainers
A plant nursery sells two sizes of oak trees to landscapers. Large trees cost the nursery $120 from the grower. Small trees cost the nursery $80. The profit for each large tree sold is $35 and the profit for each small tree sold is $30. The monthly demand is at most 400 oak trees. Furthermore, the nursery does not want to allocate more than $43,200 each month on inventory for oak trees.
a. Determine the number of large oak trees and the number of small oak trees that the nursery should have in its inventory each month to maximize profit. (Assume that all trees in inventory are sold.)
b. What is the maximum profit?
c. If the profit on large trees were $50, and the profit on small trees remained the same, then how many of each should the nursery have to maximize profit?

If he charges $60 per job, how many jobs must he do to earn a profit of at least $4,000 a month?arrow_forwardIn Example 3, if the accountant earns a profit of 100 on each individual return and a profit of 175 on each business return, find the maximum profit. An accountant prepares tax returns for individuals and for small businesses. On average, each individual return requires 3 hours of her time and 1 hour of computer time. Each business return requires 4 hours of her time and 2 hours of computer time. Because of other business considerations, her time is limited to 240 hours, and the computer time is limited to 100 hours. If she earns a profit of 80 on each individual return and a profit of 150 on each business return, how many returns of each type should she prepare to maximize her profit?arrow_forwardKenneth currently sells suits for company A at a salary of $22,000 plus a $10 commission for each suit sold.
