A company is expanding its building area from 16,000 square feet to 19,360 square feet. What is the percentage increase of the area of the building space?
so assume that 16000=100% and 19360 is x% %=parts out of 100 so 100%=100/100 16000=100% since they should be the same 16000/100=19360/x multiply both sides by x/19360 to clear fraction 16000x/1936000=1 simplify x/121=1 multiply both sides by 121 x=121
