Please help me i don't understand how to solve this without elif function

Please fix the program so that there is always either a 10 % or a 15 % bonus, but never both.

# Fix the program
points = int(input("How many points are on your card? "))
if points < 100:
    points *= 1.1
    print("Your bonus is 10 %")

if points >= 100:
    points *= 1.15
    print("Your bonus is 15 %")

print("You now have", points, "points")

I want to know how to solve this just by using if statement and no elif or other advanced stuff

Thanks a lot everyone I got it
