the plants that Lorna grew for her science project averaged 6 inches in height. Two weeks later, the plant averaged 9 inches in height. What was the percent increase in the average height of the plants?
+45 50%, I would think at least, as 50% of 6 is 3, and 6+3 is 9.
+454 I'm guess it like this so...
6 x
---- = -----
9 100
make the butter fly
100x6=600
9x=600 draw the line down its / so devide
9 9 cross out the right side now its just the left but the x stays in right
600x9=5400
x=5400
any number equals 5400 but awser is( x=5400)
