Now, we can solve further:


<em>Hence, the simplified expression is 1.02n</em>
Answer:
D
Step-by-step explanation:
The boxes with whole numbers in them written as coordinates:
(-4, -11)
(8, -8)
we know gradient is rise over run, or (y2 - y1) / (x2 - x1)
gradient = (-8 - -11) / (8 - -4)
gradient = 3 / 12
gradient = ¼
The equation representing the cost of 6 chairs and a table is:
6x + x + 50 = 750
⇒
7x = 700
This equation is true for x = 100 because:
7(100) = 700
So, the cost of one chair will be $100.
Cost of table is $50 more than a chair, so the cost of one table is $150.
So the answers are:
$ 100
$ 100
$ 150
$180 taken away from $450 is $220. the rest i'm not quite sure because there wasn't a given price for the music.
