(40) The Crane family is setting up for their fundraiser for their children's school. There will be 45 adults and 109 children coming in the evening. Each table holds 9 people. How many tables will they need for all guests?

To find out how many tables the Crane family will need for their fundraiser, we first need to calculate the total number of guests. The total number of guests is the sum of adults and children: \[ \text{Total guests} = \text{Number of adults} + \text{Number of children} = 45 + 109 = 154 \] Next, we need to determine how many tables are required to seat all 154 guests, given that each table holds 9 people. We can do this by dividing the total number of guests by the number of people per table: \[ \text{Number of tables} = \frac{\text{Total guests}}{\text{People per table}} = \frac{154}{9} \] Calculating this gives: \[ \frac{154}{9} \approx 17.11 \] Since we cannot have a fraction of a table, we round up to the next whole number. Therefore, the Crane family will need: \[ \text{Number of tables needed} = 18 \] Thus, the Crane family will need **18 tables** for all guests.
