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?Does the change show percent increase or precent decrease in the height of the plants?

Answer 1

we have that

3 inches -------> represents 100% (original value)

Applying proportion

Find out how much percentage represents the difference (7-3)=4 in

100/3=x/4

solve for x

x=(100/3)*4

x=133.33%

therefore

the percent of the change was 133.33%

Is a percent increase, because the final value is greater than the original value
