A warehouse dispatcher is arranging the delivery of 83,000 condensers. She will
use 2 large-size trucks each carrying a
minimum of 18,000 condensers. The
remaining trucks are small-size trucks, each carrying a maximum of 7,000
condensers. Each truck she uses will
make exactly one trip. Along with the 2
large-size trucks, what is the minimum
amount of small-sized trucks needed to
deliver all of the condensers. Write and
solve an equation.
