Two different-sized wheelbarrows and shovels are being used to move dirt.
Wheelbarrow A weighs 20 pounds empty
with each shovel of dirt adding 5 pounds to
its total weight. Wheelbarrow B weighs 32
pounds empty with each shovel of dirt
adding 4.25 pounds to its total weight. How
many shovels of dirt will make the total
weight of the two wheelbarrows equal?
