you can set this up with the equation;
x + (x + 42) = 138
start by combining like terms;
2x = 138 - 42
2x = 96
x = 96/2
x = 48
we've found x now plug it back into the original equation.
48 + (48 + 42) = 138
48 + 90 = 138
hope it helped...if you have any concerns just let me know:)
Each bottle contains 2 liters of the active solution. To find out how many doses can be made, divide 2 L by 4x10^-3.
The number of doses is calculated as (2 L) / (4x10^-3 L/dose) = 500 doses.
Consequently, the pharmacy is capable of preparing 500 doses of the medication.
