2b - 4*
ELLER

Step-by-step explanation:

Given expression is

To simplify any expression we combine like terms

Any expression contains constant and variables.

the terms that contains variables are 8b  and -2b .the constant term is -4

To simplify combine the like terms 8b and -2b

So the simplified expression is  

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
