Certainly! Let's walk through the problem step-by-step to determine the correct equation that shows how many cakes Sam baked this week.

1. Identify known values:
- Sam's weekly pay: $20
- Additional pay per cake: $4
- Total earnings for the week: $60

2. Define the variable:
- Let \( x \) represent the number of cakes Sam baked.

3. Create the equation:
- Sam's total earnings come from her weekly pay plus her earnings from baking cakes.
- Weekly pay: $20
- Earnings from cakes: $4 per cake times the number of cakes (\( 4x \))

4. Formulate the total earnings equation:
- Total weekly earnings = Weekly pay + Earnings from cakes
- Total weekly earnings = [tex]$20 + $[/tex]4 \times x$

5. Set up the equation based on the total earnings:
- Since Sam earned a total of $60, we can write:
[tex]\[ 20 + 4x = 60 \][/tex]

Thus, the correct equation that represents the number of cakes Sam baked this week is:
[tex]\[ 20 + 4x = 60 \][/tex]
