Your answer is D.


The jeans are 40% off (because you add 20% more).

And the original cost of the jeans is $30.


You could have done:

30 · 0.40 = 12  (Find 40% of $30, then subtract 30 by 40% of 30 to get the new sale price]

30 - 12 = 18


1 - 0.40 = 0.60  (You subtract 1 by 0.40 to get 0.60, which is the % of the original price that you have to pay)

30 · 0.60 = 18

taurus [48]

Answer:

The number of edges is E=12

Step-by-step explanation:

we know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

so

V- E + F = 2

In this problem we have

F=8, V=6

substitute and solve for E

6- E + 8 = 2

E=6 + 8 -2=12
