Question

Ricky grows plants for a science project at the start of his project the plants average a height of 3 inches after three weeks the average player height was 7 inches what was the percent of the change in the average height of the plants?

Answer 1

To answer this question, we will use the following formula for the percent of change:

`P=(F-I)/(I)*100,`

where F is the final height and I is the initial height.

Substituting F=7, and I=3 we get:

`P=(7-3)/(3)*100.`

Simplifying the above result we get:

`F=(400)/(3)\text{.}`

Answer: 400/3 %.
