Answer:
$0.05
Step-by-step explanation:
1. Since we want to find how much 1 single sticker costs, and 20 stickers equal 1 dollar, let's write it as a ratio: [tex]\frac{20}{1} = \frac{1}{x}[/tex]
2. Now, let's solve the ratio.
- [tex](20)(x) = (1)(1)[/tex]
- [tex]20x = 1[/tex]
- [tex]\frac{20x}{20} = \frac{1}{20}[/tex]
- [tex]x = 0.05[/tex]
Therefore, one sticker costs $0.05.
