1) we have to calculate the increase of the cost of the jacket.
Increase of the cost of the jacket=new price - previous price
increase of the cost of the jacket=$87.75 - $75.00=$12.75
2)Now, we calculate the percentaje incresae of the costo of the jacket by the rule of three.
$75=100%
$75------------------100%
$12.75------------- x
x=($12.75 * 100%) / $75=17%
Answer: the percentage increase of the cost of the jacket is 17%
Answer:
A) 8
Step-by-step explanation:
The average of two numbers is 7.
6 and x have an average of 7.
sum of terms / number of terms = average
(6 + x)/2 = 7
6+x = 14
x = 8
The number is 8.
Answer:
$43.66 rounded to the nearest 10 =$40
15% of $40 = $6
Step-by-step explanation:
Answer:
The two ordered pairs you can use is (4, 3) and (8, 4). You can plot these and draw a straight line through these.
Step-by-step explanation:
In order to find the graph of the follow, first solve for y.
-8 + x = 4y - 16
-4y - 8 + x = -16
-4y -8 = -x - 16
-4y = -x - 8
y = 1/4x + 2
Now that we have this, we can find two points by choosing any two x's and solving for the y. For this case, we'll use 4 and 8.
y = 1/4x + 2
y = 1/4(4) + 2
y = 1 + 2
y = 3
So the first ordered pair is (4,3)
y = 1/4x + 2
y = 1/4(8) + 2
y = 2 + 2
y = 4
So the second would be (8. 4)
