Question

Carlos and his friends are thinking about taking a cab home. The Cost for the cab ride is $1.50 per mile

Question:
Write a formula that will help Carlos Determine how much each friend will have to pay for the cab ride.
x=number of miles traveled
y=number of friends in the cab
z=cost of each friend

Answer 1

Explanation:

x=number of miles traveled

y=number of friends in the cab

z=cost of each friend

If carlos and his friends travel the same distance, x, then the total cost of the cab is x*1.50.

if there are y friends in the cab, then we must divide the total of the cab by the number of people inside that traveled to obtain the cost of each one.. it is z = x*150/(y+1)

notice that i used y + 1, that is because there are y friends and carlos, so the amount of money is divided by y + 1.
