While shopping with her husband (see practice e), Mrs. Garantua
bought 2 garden hoses (one to use as a neclace and the other to
use a leash for her pet whatchamacallit) and 2 giant flowerpots
(both to use as summer hats). If the hoses cost $30 each, and
the bill for all the items (hoses and flowerpots combined) was
$96, how much did each flowerpot cost?
