Plz help me with problems. highly appreciate it

lol I already did it ok why not

Step-by-step explanation:

number 1 = increase 233.3 percent

number 2= increase 122.2 percent

number 3= decrease 15.0 percent

number 4 = decrease 55.5 percent

number 5 =increase 100 percent

page 2

number 6 = 15 / 55 times 100 = 27.2 percent decrease

number 7. 20 / 230 times 160 = 13.9 percent increase

number 8. 2.06 / 94 times 100 = 219.9 percent increase

number 9. 4,500 / 45,000 times 100 = 10 percent increase

number 10. 500 times .20 = 400$

b. 80 / 400 = 20 percent decrease

page 3

c 320- 290= 30 / 320 = .093 = 9.4 percent decrease

11. 150

12. 12.49

13. 9/15 100/115 = 13

14. 60/.6 = 100$

the solution is h=10 because you add 9 to each side of the equation.
