Question

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?

Answer 1

It would be 1649.04 cause 824.52+824.52=

Answer 2

Answer:
`\$549.68`

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:

`Total\ cost=2(\$824.52)\\\\Total\ cost=\$1,649.04`

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:

`b=(Total\ cost)/(3)\\\\b=(\$1,649.04)/(3)\\\\b=\$549.68`
