The easiest way to answer this question is by rounding $5.99 and $7.99 to $6.00 and $8.00. Then multiply 3 by 6 and 5 by 8. 
. Now to find the exact answer, seeing as $5.99 is 1 cent away from $6.00 and $7.99 is one cent away from $8.00, we can do 
and 
, we can see that $49 is 8 cents over. From there we subtract the 8 cents from the $49 and see that the amount she spent on downloads was $48.92.

Okay so the y is in absolute value, which means the number could be a negative and the absolute value would make is a positive.
since the sign is greater than, with no equal to underneath it, than the answer cant be 3 or -3.
the number has to total to be larger than 3. again, since the absolute value turns the negatives into positives, then -4 is an acceptable answer. so the absolute value line should look like the above (please excuse the terrible look). I simplified it to the two numbers that start the equation. the two circle are open circles because the sign does not include an equal sign under it. you draw the arrows on either side of the two numbers because any answer beyond those arrows fits in with the equation
