Question

There were 35 tomato plants in the gardenSome died and now there are only 28. What isthe percent of change?

Answer 1

initial quantity of tomato is 35

final quantity = 28

so the percentage change is,

`=(28-35)/(35)*100`
`\begin{gathered} =(-7)/(35)*100 \\ =-20\text{ \%} \end{gathered}`

so the percentage change is -20%

the negative sign is showing the decrement in the quantity
