Answer:
6
Step-by-step explanation:
To find how many perennials there are, multiply the amount of plants by the percent of perennials. When you multiply percents, just put the percent behind the decimal
60x0.35=21
There are 21 perennials
Do the same for the biennials:
60x0.25=15
Therefore 15 biennials
Subtract the amount of perennials from the amount of biennials
21-15=6
There is 6 more perennials than biennials
