Answer 1

To find the amount earned for selling 4, 9, and 14 bags of chips using the equation \( d = 0.60n \), we will substitute \( n \) with the values given (4, 9, and 14) and calculate \( d \).

1. For \( n = 4 \): \[ d = 0.60 \times 4 = 2.40 \] So, for 4 bags, they earn $2.40.

2. For \( n = 9 \): \[ d = 0.60 \times 9 = 5.40 \] So, for 9 bags, they earn $5.40.

3. For \( n = 14 \): \[ d = 0.60 \times 14 = 8.40 \] So, for 14 bags, they earn $8.40.

Now you have the amounts:

• For 4 bags: $2.40
• For 9 bags: $5.40
• For 14 bags: $8.40

You can enter these values into Zearn as needed.
