3-4. This summer, local children can sign up for art or music lessons for a ___ fee of $3. It’s impossible to take both, though, since the classes will be ___.

What are your choices?

To solve this problem, we need to fill in the blanks with the missing information. The first blank asks for the fee of signing up for art or music lessons, while the second blank mentions that it is impossible to take both classes.

Let's address the first blank. The fee for signing up for art or music lessons is given as a blank. To determine the fee, we need to find the missing number from the information provided. The phrase "a ___ fee of $3" indicates that the fee is $3. Thus, we can fill in the first blank with the number $3.

Moving on to the second blank, it states that it is impossible to take both classes. This means that if a child chooses art lessons, they cannot take music lessons, and vice versa. Therefore, the missing word is "impossible" since it describes the situation.

Putting it all together, the completed sentence becomes: "This summer, local children can sign up for art or music lessons for a fee of $3. It's impossible to take both, though, since the classes will be impossible."
