Answer:

39%

Step-by-step explanation:

Let's find the answer by using the following formula:

selling price=(paid price)+((paid price)*(percent markup)) which can be written as:

percent markup=((selling price)-(paid price))/(paid price)

percent markup=(27.80-20)/20

percent markup=0.39=39%

In conclusion, the percent markup is 39%.

Solve the system using the elimination method.
Sloan [31]

Answer:

x=151/64   y=9/8 z=-51/32

Step-by-step explanation:

2x+2y+5z- (2x-y+z)=-1-2

3y+4z=-3

2x+2y+5z- (2x+4y-3z)=-1-14

-2y+8z=-15

We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)

3y+4z=-3 (2)

-2y+8z=-15 (-3)

6y+8z=-6

6y-24z=45

(6y+8z)- (6y-24z)= -6-45

32z=-51

z=-51/32

3y-204/32=-3

3y= -96/32+204/32

3y=108/32

y=36/32=9/8

2x+2*9/8+5*(-51/32)=-1

2x+9/4-255/32=-1

2x+72/32-255/32=-1

2x-183/32=-32/32

2x=151/32

x=151/64
