Ex. On Earth Day, a nursery sold more than $1500 worth of maple
and birch trees. The maple trees were sold for $75 and the birch
trees were sold for $50.
a) Write a linear inequality to represent the possible combinations of
trees sold. Are there any restrictions?
b) Graph the inequality.
c) Use the graph to determine:
i) Could the nursery have sold 13 of each type of tree?
ii) If 14 of one type and 9 of the other type could have been sold.
