To calculate the total cost of the photographer for 1 to 5 poses, we can use the formula:
\[ \text{Total Cost} = \text{Sitting Fee} + (\text{Cost per Pose} \times \text{Number of Poses}) \]
Given that the sitting fee is $15 and the cost per pose is $3, we can calculate the total for each number of poses:
-
For 1 pose: \[ \text{Total Cost} = 15 + (3 \times 1) = 15 + 3 = 18 \]
-
For 2 poses: \[ \text{Total Cost} = 15 + (3 \times 2) = 15 + 6 = 21 \]
-
For 3 poses: \[ \text{Total Cost} = 15 + (3 \times 3) = 15 + 9 = 24 \]
-
For 4 poses: \[ \text{Total Cost} = 15 + (3 \times 4) = 15 + 12 = 27 \]
-
For 5 poses: \[ \text{Total Cost} = 15 + (3 \times 5) = 15 + 15 = 30 \]
Now we can compile the results for 1 to 5 poses:
- 1 pose: $18
- 2 poses: $21
- 3 poses: $24
- 4 poses: $27
- 5 poses: $30
Thus, the range of total costs for 1 to 5 poses is:
\[ \text{range} = {18, 21, 24, 27, 30} \]
This matches the second option you provided:
range = {18, 21, 24, 27, 30}.
