You can put this solution on YOUR website! there are many ways to solve this problem
let me show you one way.....
so if 2500=100x, then 2500/100=x ok?
2500/100= 25/1= 25. that means x=25. YOu can even check it-- does 100*25=2500?
now that we know x, 4500+80(25), now you can solve that equation. FIRST you multiply 80(25)=y. once you get that number (y, which is the product of 80 and 25) you add 4500, 4500+y. I hope this isn't confusing. 80(25)=2000. 2000=y. y+4500=? now I'll leave that for you.
