Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
Answer: Your question is missing information but this is what you do to answer your question step by step
B = Cost of 8 pack / 8 bottles = $ Cost of 8 pack/ 8 =$ ____ per bottle
A = Cost of 6 pack/ 6 bottles = $ Cost of 6 pack/ 6= $ ____ per bottle
then do a simple subtraction A -B = savings
Step-by-step explanation: Information is incomplete
if an 8 pack cost $16
If the 6 pack cost $15
All you do is a simple subtraction after calculations
Cost of 8 pack / 8 bottles = $16/8 =$2 per bottle
Cost of 6 pack/ 6 bottles = $15/ 6= $2.50 per bottle
in my example
You would save $ 0.50 per bottle by purchasing the 8 pack
Bowling costs 15 dollars per person and 3 is amount of money per game it cost to play. If you play 5 games then you pay a total of 30 dollars.
