To calculate the media mail cost:
\[ C = 2.66 + 0.51 \times (W - 1) \]
Media mail is mail that contains any of the following types of media:
Let's assume the following value:
Step 1: Subtract 1 from the weight:
\[ W - 1 = 3 - 1 = 2 \]
Step 2: Multiply the result by 0.51:
\[ 0.51 \times 2 = 1.02 \]
Step 3: Add $2.66 to the result:
\[ C = 2.66 + 1.02 = 3.68 \text{ dollars} \]
Let's assume the following value:
Step 1: Subtract 1 from the weight:
\[ W - 1 = 5 - 1 = 4 \]
Step 2: Multiply the result by 0.51:
\[ 0.51 \times 4 = 2.04 \]
Step 3: Add $2.66 to the result:
\[ C = 2.66 + 2.04 = 4.70 \text{ dollars} \]
