To find Heather's weekly salary, we can use the information that $20 is 5% of her salary.
1. Let's set up an equation to represent this:
- Let x be Heather's weekly salary.
- Since $20 is 5% of her salary, we can write this as an equation: 0.05x = $20.
2. To find x (Heather's weekly salary), we need to solve for x in the equation 0.05x = $20.
- Divide both sides of the equation by 0.05 to isolate x: x = $20 ÷ 0.05.
3. Calculating this, we get:
- x = $400.
Therefore, Heather's weekly salary is $400.
