Question

Sal and two of his friends rent an apartment together. Their total cost to move in included first month's rent, last month's rent and a security deposit of $1,200. If Sal paid a total of $1,000 to move in, how much is his share of the rent each month? a. $300 b. $450 c. $600 d. $900

Answer 1

a.

$300

Explanation:

Answer 2

Option a. $300

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`
