Question

the daily supply of oxygen for one person is provided by 625 square feet of lawn. a total of 4375 square feet of lawn would provide the daily supplies of oxygen for how many people?

Answer 1

If the oxygen produced by 625 ft^2 of lawn, and 4375 ft^2 is the total lawn you have, you can use the following equation to figure out how many people the lawn can support:

4375 ft^2 = (625 ft^2)x, with x being the people being supported

4375 ft^2 / 625 ft^2 = x

x = Seven people
