Answer 2

Answer:

Option a. $300

Step-by-step explanation:

Let

x ----> the cost of the rent monthly per person

we know that

The number of persons is 3 (Sal and two friends)

The cost of the security deposit per person is equal to

$\ 1,200/3=\ 400$

If Sal paid a total of $1,000 to move in

then

That means that the cost per person of two months of rent (first and last month) plus $400 (security deposit per person) must be equal to $1,000

$2x+400=1,000$

solve for x

$2x=1,000-400\\2x=600\\x=\ 300$
