### First, I would need to find out what is 20% of 80. So I can use the multiplication method, which is 0.20 (20% in decimal form) multiplied by 80. which gives me \$16. Since I’m increasing it from \$80, I would add \$16 + \$80 which is \$96.

### Since this is percentage decrease, I would subtract 16 from 80. 80 -16 = \$64.
