Question

The cost to rent a vacation house for a week is 850$. How much will Renee , susan and Martha each pay to rent this house for a week

Answer 1

I assume they are splitting up the cost of $850 to rent the house.
Let x represent cost to rent one house for one week.
Since there's three people each renting a house for a week, you would have
3x = 850
x = 283.333
$283.34
