Write a formula that will help them decide how much each friend will have to pay.
Let's let
w = price per mile
x = number of miles traveled
y = number of friends in the cab
z = cost for each friend

Sagot :

Okay so since we have all the variables, we can go ahead and make our formula. So our equation would look like z = (w/x) divided by y . This is because z would be the sum of the x miles divided by the cost of each mile (w). And then we would divide what we got in the parenthesis by y (friends).
