The scale factor of the dimensions of two similar wood floors is 5 : 4. it costs $352 to refinish the smaller wood floor. at that rate, how much would it cost to refinish the larger wood floor?

What situation is an example of an observational study

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?

How can constraints be used to model a real-world situation?
