-35 is < -23.
-35 is less than -23.
-23 is closer to 0 on the number line with 12 steps than -35.
First, you find what 25% of $450.To do that, make 25% into a decimal, which is 0.25.Then you multiply 450 times 0.25 which is 112.5
Second, you find what 5% of 450. 5% as a decimal is 0.05. Then you multiply 450 times 0.05 which is 22.5
Third, you add 450+112.5+22.5 which is 585.
There you go. :) Hope that helped!
