12.2 I believe but I'm not sure
The price of tablet was $250 before mark down.
Step-by-step explanation:
Given,
Mark down = 15%
Price after mark down = $212.50
As price is marked down 15% from 100%, we can say that
(100-15)% = 85% is the price after markdown.
Let,
x be the original price.
Therefore,
85% of x = 212.50
Dividing both sides by 0.85
The price of tablet was $250 before mark down.

Answer:
B D F
Step-by-step explanation:
I dont really know how to explain it, and I need to reach 20 characters for an answer so pretend this is a good explanation
Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has
we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3
substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4
y=11+z----> equation 3
2y+z=40-----> equation 4
resolves the equations system
using a graph tool
see the attached figure
the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22
the answer is<span>
Denise has $17</span>
