have 2 coworkers who are each willing to pay for one-third of the tank each month to carpool with

you. What is your share of the total gas price?

Share of gas

keep messing up and don't know where I am making the mistake someone please help and explain.

You m multiply the gallon price times the amount of gallons, which in this case is 18. That equals 57.42. Sonce the coworkers pay 1/3 each, just divide 57.42 by 3 and that is how you get 19.14.

Answer:

$19.14

Step-by-step explanation:

You want to know the amount of a 1/3 share of the cost of 18 gallons of gas at $3.19 per gallon.

One-third

There are several ways to figure this. One of the simplest is to divide the quantity of gas by 3. Your 1/3 share of 18 gallons is 18/3 = 6 gallons of gas.

The cost of 6 gallons of gas is ...

(6 gal)($3.19/gal) = 6×$3.19 = $19.14

Your share of the gas cost is $19.14.

Additional comment

You can also figure the total cost of gas as (18 gal)(3.19/gal) = 57.42. Then you can divide that by 3 to find the amount of each share.

Once you have the share amount, you can either stop (because you owe one share), or you can subtract the two co-workers' shares from the total to find your share. (The result is still one share.)

57.42 -2(19.14) = 19.14 . . . . your share.
