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?
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%.
