Answer:
40
Step-by-step explanation:
We have an original price p
We mark them up by 50%
p + p*50%
Changing to decimal form
p+.50p = 1.5p
The new price is 60 dollars
1.5p = 60
Divide each side by 1.5
1.5p/1.5 = 60/1.5
p =40
The original price is 40
$40
Let C be the cost
150% of C = 60
150/100 × C = 60
C = 60 × 100/150
C = 40
The vertex is (-4,-3)
The axis of symmetry is x=-4
and the transformations are:
C
I took the test
:)
x = 30
30 + 2x = 90
2x = 60
D) (–5,0), (0,2), (5,0), (0,–2)
The vertices are basically the x and y intercepts.
