Answer:
A. $58.50
B. $80
C. No. The markup was 33 1/3%
Step-by-step explanation:
You are expected to know the relevant relationship is ...
cost + markup = selling price . . . . also called "store price" in this problem
___
A. The markup is 30% × $45 = $13.50, so the store price is ...
$45 + 13.50 = $58.50
___
B. When the 30% markup is added to the 100% cost, the selling price is 130% of the cost, or 1.30 times the cost. Here you have ...
$104 = 1.30 × cost
$104/1.3 = cost = $80 . . . . . divide by the coefficient of cost
___
C. The markup is $100 -75 = $25, so the markup percentage based on cost is ...
$25/$75 × 100% = 33 1/3%
This is not 30%.
Step-by-step explanation:
Answer:
The answer to your question is: F = (-6, -4)
Step-by-step explanation:
Segment = EF
mpM = (-2, 2)
first point = E = (2, 8)
second point = F = (x, y)
Formula
Xmp = (x1 + x2) / 2 Ymp = (y1 + y2) / 2
x2 = 2xmp - x1 y2 = 2ymp - y1
Process
x2 = 2(-2) - 2 y2 = 2(2) - 8
x2 = -4 - 2 y2 = 4 - 8
x2 = -6 y2 = -4
F = (-6, -4)
Answer:
Step-by-step explanation:
Multiply by x^2 on both sides
9x^2+27x+8=0
Factor.
The answers are -1/3, -8/3
