A business is planning to provide sandwiches at their company picnic. Adults eat 1 3/4 times the amount that school-aged children eat, and babies eat half of what school-age children eat. 56 adults, 14 school-age children, and 28 babies are attending the picnic. If adults eat 5/8 of a sandwich, how many sandwiches should be ordered?
