For what value of a does 9 -
27
?
11
3

The first one is the answer

10b is the number of bottles of water, plus the 45 you already spent and this has to be less than 65

10b + 45 < 65

10b < 65 - 45

10b < 20

b < 2

so the most amount of money you can spend on the water is less than 2 dollars, so 1.99

on the number line, you'll have to write out numbers and at 2, draw an empty circle above it and a line going backwards

hope i helped!
