Question

Savanna had 40 iris blooms last year. This year she had 15% more iris blooms. How many more iris blooms did Savanna have this year?

Answer 1

40*15%=6

40+15%=46

hope one of these helped

Answer 2

To solve this problem what you can do is the following rule of three:
 40 iris blooms -----> 100%
 x iris blooms -------> 115%
 Clearing the value of x we have:
 x = (115/100) * (40)
 x = 46
 Then, comparing with last year we have:
 40-46 = 6
 Answer: 
 Savanna had this year 6 more iris blooms than last year.
