Answer:
Savanna had 6 more iris blooms this year
Step-by-step explanation:
We are given that:
Last year, she had 40 iris blooms
This year, she has 15% more iris blooms than last year
This means that:
This year she has = (40 + 15% of 40) iris blooms
This year she has = 40 + 0.15(40)
This year she has = 40 + 6 = 46 iris blooms
Now, we get the increase in the number of blooms:
Increase = amount she has this year - amount she had last year
Increase = 46 - 40 = 6 iris blooms
Hope this helps :)
