PLEASE HELP
Goshia [24]

Answer:

Original cost was $19.99

Step-by-step explanation:

100% - 15% = 85%

16.99 / 0.85 = 19.99

To check:

19.99 * 0.15 = 2.998

19.99 - 2.998 = 16.992 = 16.99

Correct!!

Help please im stuck
serg [7]
If the two equations have the same solution, they will have the same x value that makes them true. So solve for x for both equations and see if they are equal:

8x=87 \\
x=10.875

\frac{2}{3} x+ \frac{3}{4} =8 \\
 \frac{2}{3} x=7.25 \\
x=10.875

Because both equations have the same x value, they have the same solution.
