Question

The invitations to a holiday party cost a total of $31.50. If each invitation cost $0.75, how many invitations were sent out?

Answer 1

To find out how many invitations were sent out, we can use the formula:

\[
\text{Number of invitations} = \frac{\text{Total cost}}{\text{Cost per invitation}}
\]

Given:
- Total cost = $31.50
- Cost per invitation = $0.75

Substituting the values into the formula gives:

\[
\text{Number of invitations} = \frac{31.50}{0.75}
\]

Now we can perform the division:

\[
\frac{31.50}{0.75} = 42
\]

Thus, the number of invitations sent out is

\[
\boxed{42}
\]
