Answer: The expression for the retail price of a silver chain is 1.4c.
Step-by-step explanation:
Let the amount of jewelry be c dollars.
Rate of mark up = 40%
So, Amount of mark up would be
times c
= 0.4c
So, Amount after mark up would be
c+0.4c
=1.4c
Answer: The expression for the retail price of a silver chain is 1.4c.
Answer is (3,1)
x + y = 4
2x + 3y = 9
We multiply the first equation by -2 to eliminate x
-2x - 2y = -8
2x + 3y = 9
-------------------(add both equations)
0 + y = 1
So y =1
Now plug in 1 for y in first equation
x + y = 4
x + 1 = 4
Subtract 1 on both sides
x = 3
Answer is (3,1)
The area is 8. All you have to do is multiply 3 1/2 by 8.
Good luck!
