Step-by-step explanation:
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!!
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:


Because both equations have the same x value, they have the same solution.
T=k/s
So k/36 = 2
k = 72
Put into original equation
t= 72/3 (s is 3)
So t is 24
