Lets say that J is for Jennys messages, B is for Boris’ and E is for Erics (or Ericas?).
79 = J + B + E
J = E - 6
B = 3E
Since both Jenny’s and Boris’ number of text messages has some kind of relation to Eric’s number of messages, we can say that:
79 = E - 6 (Jenny) + 3E (Boris) + E (Eric), so:
79 = E - 6 + 3E + E /combine like terms
79 = 5E - 6 /add 6 to both sides
79 + 6 = 5E /switch sides + combine like terms
5E = 85 /divide both sides by 5
E = 85/5
E = 17
So, Eric sent 17 messages. Lets get back to those equations we made for Jenny and Boris:
J = E - 6 = 17 - 6 = 11
B = 3E = 3 * 17 = 51
And we can check if it adds up: 51 + 11 + 17 = 79, which is what we were supposed to get.
profit on the twenty-five $50 radios
= 25*(50*0.08)=$100
Loss on the six $30 radios
= 6*(30*0.15) = $27
Combined result of both transactions
= $100-27
=$73 (profit)

Answer: (x - 5, y - 6)</h3>
=====================================
Explanation:
Let's say that point P is at (0,0). Using the original rule (x+5, y+6), we would add 5 to the x coordinate and 6 to the y coordinate to land at (5,6) which is point P '
Now the teacher wants you to start with point P ' and move back to point P. The rule to do this is basically the inverse or opposite of what the original rule states.
Instead of "add 5 to x", we "subtract 5 from x" to have x-5 as part of the rule. Similarly, undoing "add 6 to y" means we have "subtract 6 from y" to have y-6.
That's how (x-5, y-6) is the complete opposite or inverse of (x+5, y+6)
The first rule shifts P five units to the right and six units up to land on P'
The second rule moves P ' five units to the left and six units down.
If you apply either rule in any order, but do so together, then the point always goes back to its original starting location.

Answer:
$60,000 ( 50% loss)
Step-by-step explanation:
If Stacy Tanner had a capital decrease of $30,000 and still having $30,000 after closing entries, this explains that $60,000 would have remained after closing entries.
If $60,000 would have remained, it means that, as calculated below:
If 100% where to be generated as capital = $60,000
then % loss, that is, $30,000 = 100 X 30,000/60,000 = 50%
