Quick Copy SUMIFS

Hello! I am an excel novice. So please excuse any absurdity.
I have a SUMIF formula that I'd like to repeat.

Column A states a number:
"11.00
11.51
11.98
11.99
xx.00
xx.51
xx.98
xx.99
xx.00
xx.51
xx.98
xx.99"

This pattern continues through 300:
"300.00
300.51
300.98
300.99"

I have a SUMIF formula:
SUMIFS(B:B,A:A,">=11.00",A:A,"<11.50")
SUMIFS(B:B,A:A,">=11.51",A:A,"<11.97")
SUMIFS(B:B,A:A,"11.98")
SUMIFS(B:B,A:A,"11.99")

I need to copy the formula down to 300. Currently if I drag it down, the numbers stay the same. I need the numbers to automatically update in the formula as it is copied as opposed to manually typing in the updated number:
"SUMIFS(B:B,A:A,">=11.00",A:A,"<11.50")
SUMIFS(B:B,A:A,">=11.51",A:A,"<11.97")
SUMIFS(B:B,A:A,"11.98")
SUMIFS(B:B,A:A,"11.99")
SUMIFS(B:B,A:A,">=12.00",A:A,"<12.50")
SUMIFS(B:B,A:A,">=12.51",A:A,"<12.97")
SUMIFS(B:B,A:A,"12.98")
SUMIFS(B:B,A:A,"12.99")
SUMIFS(B:B,A:A,">=13.00",A:A,"<13.50")
SUMIFS(B:B,A:A,">=13.51",A:A,"<13.97")
SUMIFS(B:B,A:A,"13.98")
SUMIFS(B:B,A:A,"13.99") so on and so forth through 300....


I've attached a spreadsheet that has all the factors in it. Thank you for any help!
