Dale, thomas, and betty plan to split the cost of a round-trip car ride from
oklahoma city, oklahoma to sturgis, south dakota, equally. the total cost of
the trip from oklahoma city to sturgis was $824.52, and they expect that the
trip back to will cost the same. how much will betty have to pay for the round-
trip?

Step-by-step explanation:

Let be "b" the amount of money (in dollars) that Betty will have to pay for the round-trip.

According to the information provided in the exercise, the total cost of the trip from Oklahoma City to Sturgis was $824.52.

So, it the cost of the trip back will be the same, the total cost of the round-trip will be:

Since the exercise indicates that they plan to split that total cost for the round-trip in equal parts, you need to divide the Total cost of the round-trip by 3, in order to find "b".

Therefore, you get the following result:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
