Step-by-step explanation:

1. Increase amount = 40-25=15 Increase percent = (15/25)×100%= 60%.

2.Increase amount = 30-15 = 15. Increase percent = ( 15/15)× 100% = 100%.

3. Increase amount= 50-18=32 Increase percent= (32/18) x100% = 177.77%

4. Increase amount= 80-22=58 Increase percent= (58/80) x 100% = 72.5% > 73% (when rounded of to the nearest 10's).

5. Increase amount= 18-16=2 Increase percent = (2/18)×100 %= 11.111...% > 11% (when rounded of to the nearest 10's).
