So first you want to do the cost of each foot times the number of feet 112 * $1.59 = $178.08

Then do the subtraction $200.00 - $178.08 = $21.92

Therefore, the answer is C

Write the system of linear equations shown by the graph. Use slope-intercept form.

Andre45 [30]

The required system of linear equations is y = -4x + 1 and y = 5x - 8.

Given that,
From the graph,
system of linear equation is to be determined.

Here,
The slope-intercept form of linear equation.
y = mx + c - - - - - (1)

Equation of line 1
Since point (-1, 5), (0, 1) lies on the line 1.
The slope of line 1,
m = 1-5 / 0+1
m = -4
Now put this slope and 1 point in the equation.
5 = -4(-1) + c
c = 5 - 4
c = 1
now, put m and c in equation 1
y = - 4x + 1

Similarly, the equation of line 2 is given as y = 5x - 8.

Thus, the required system of linear equations is y = -4x + 1 and y = 5x - 8.

The cost of a laptop computer in 2007 was $1,250. In 2009, the price decreased to $1,100.

sashaice [31]

Given : The Cost of Laptop in 2007 is $1250

Given : The Cost of Laptop in 2009 is $1100

Decrease in Price of Laptop from 2007 to 2009 : (1250 - 1100) = $150
