You set up the equation like this:
T/45+T/53=1
You find the least common factor of 53 and 45 and times both sides so you end up with this:
53T+45T= least common factor
Then add up 53T and 45T.
98T= least common factor
Then divide 98 from both sides. That will be your answer.
Sorry I didn't have enough time to find the least common factor but it is a number that they both go into. I would check to make sure I'm correct. I hope this helps!
26,500 - 19,610 = 6,890
6,890 would be your price discount, but now you'd have to find your percent discount. Make it into an equation to make things easier.
6,890/26,500 = p/100
(6,890*100)/26,500 = p
6,890*100 = 689,000
689,000/26,500 = 26
The price discount would be 26%.
