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

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

solve for x

So let's say the amounts are "a" and "b", at 6% and 8% respectively.
how much is 6% of a? well (6/100) * a, or 0.06a.
how much is 8% of b? well (8/100) * b, or 0.08b.
so hmm whatever "a" and "b" amounts are, we know that their yield is $100, thus
0.06a + 0.08b = 100.
now, there's more money in "a" than in "b", 500 bucks more, so whatever "b" is, we know that
a = b + 500.

how much was deposited in the 6% one? well, a = b + 500.
Answer:

Step-by-step explanation:
P, A, and R are collinear.
PR = 54


To solve for the numerical length of PR, let's generate an equation to find the value of x.
According to the segment addition postulate:

(substitution)
Solve for x

Combine like terms


Add 2 to both sides


Divide both sides by 7



Plug in the value of x into the equation


Here is a proportion
5/2 = x/8
2x = 40
/2 /2
x = 20
