Answer:
Option b
or 
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function 
x> 0 for all real numbers.
Then the equation:
has two cases
if 
(i)
if 
(ii)
We solve the case (i)
We solve the case (ii)
Then the solution is:
or
Given that t<span>he
function b(n) = 12n represents the number of baseballs b(n) that are
needed for n games.
Then the number of baseballs needed for 15 games is given by b(n) = 12(15) = 180.</span>
