It is a rule of thumb that each person occupies 2.5 square feet – that is the unit rate of people per square foot is .4 people/sq ft. Busby Barkley is putting on an extravaganza in which he will have 250 dancing, singing chorus girls. What assumptions would you need to make to use the .4 person/sq ft approximation?

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
