You would do percent of change.
meaning you would subract 65 and 50 to get 15. then you would put 15 over 50 (as a fraction) then equals r/100. then you would cross multiply to get r.
orginal:50
new:65
65-50=15
15/50=r/100
15r=5000
then divide by 15 to get r
I believe it would be 999,999

Answer:
8
Step-by-step explanation:
=z²-3z+4 when z is 4
=4²-3(4)+4
=16-12+4
=8
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
