Step-by-step explanation:

10) 170 is greater than 150 by 25. 25 is $16\frac{2}{3}$% of 150, so it increased by appoxamately 17%.

11) 225 is decreased by 45. 45 is 20% of 100, so 255 decreased by 20%

12) 15 is increased by 10. 10 is $66\frac{2}{3}$ of 15, so 15 increased by $66\frac{2}{3}$%

13) 5% of 9,000 is 450. 450 + 9,000 is $9,450

14) 7% of 140 is is 9.8. 140 + 9.8 = $149.8

15) 6% of 225 is 13.5. 225 + 13.5 = $238.5
