Answer: $4.75.
Step-by-step explanation:
It is given that a news offers a subscription that costs $28.50 for 6 months.
We need to find the unit price per month.
The formula for unit price per month is
[tex]\text{Unit price per month}=\dfrac{\text{Total subscription cost}}{\text{Number of months}}[/tex]
[tex]\text{Unit price per month}=\dfrac{28.50}{6}[/tex]
[tex]\text{Unit price per month}=\dfrac{285}{60}[/tex]
[tex]\text{Unit price per month}=4.75[/tex]
Therefore, the unit price per month is $4.75.
