Bot a rosebush has 4 roses the first year it is planted. The following year, the rosebush has 9 roses. What is the percentage increase in roses from the first year to the second year?

Answer 1

To calculate the percentage increase in roses from the first year to the second year, we need to find the difference in the number of roses and then express it as a percentage of the initial number of roses.

The difference in the number of roses is 9 - 4 = 5 roses.

To express this as a percentage of the initial number of roses, we divide the difference by the initial number of roses and multiply by 100:

(5 / 4) * 100 = 1.25 * 100 = 125%.

Therefore, the percentage increase in roses from the first year to the second year is 125%.
