Increase.

1/4 can be translated to 25%

1/2 can be translated to 50%

25% to 50% is an increase.

nasty-shy [4]

Answer:

$1100

Step-by-step explanation:

Let the rent be x

Discounted rent

x - $50

Increase applied

Final rent:

(x - 50) + 10% = (x - 50)*1.1

We know this is equal to x + 5% = 1.05x, comparing now

1.1(x - 50) = 1.05x
1.1x - 1.05x = 55
0.05x = 55
x = 55/0.05
x = $1100

Use technology to find points and then graph the line y=-5(x-5)+1 following the instructions below.

Svetach [21]

Given:

$y=-5(x-5)+1$

First, let us find two points from this equation.

We can set values of x and then solve for y.

Let us find the values of y when x = 1, 2, 3, 4, 5

$\begin{gathered} y=-5(x-5)+1 \\ y=-5(1-5)+1=21 \\ y=-5(2-5)+1=16 \\ y=-5(3-5)+1=11 \\ y=-5(4-5)+1=6 \\ y=-5(5-5)+1=1 \end{gathered}$

We now have a set of points:

(1, 21)

(2, 16)

(3, 11)

(4, 6)

(5, 1)

Since the given plane is limited to values of 10 and -10, the points that we can plot are the points (4, 6) and (5, 1)

The graph would then look like this:
