The store bought an IPad for $900 and sold it for $1200. What percentage was
the mark-up?

answer: The mark up percentage was 25% because if you find how much 900 is of 1200  which is 75% and subtract it by 100% which is 25%. To check your work you can multiply 25% *  1200 which equals 300 then add 300 to 900 which Equals 1200.

Just add the two numbers and it will give the answer 2100:

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
