Markup= original cost x percentage markup

Selling price= original cost + markup

The manufacturing cost of a cell phone was $124. Sellers first marked up the cost by 20 percent . Sales were poor so sellers decreased the markup to 15 percent . Calculate the old and new selling prices .

A. Old price $170.00; new price $148.80

B. Old price $142.60; new price $148.80

C. Old price $148.80; new price $142.60

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

a.)the line for function b is steeper

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
