Alex is having a birthday party. He purchased 3 1/2 gallons of soda for $4.50 per gallon, 2 cakes for 14.99 each, and 8 pizzas for $16.49 each. How much did he spend in total on the pizza and soda? 

To find how much Alex spent in total on the pizza and soda, let's break down the problem step by step:

### Step 1: Calculate the cost of soda
Alex purchased $3 \frac{1}{2}$ gallons of soda at $4.50 per gallon.
\[
3 \frac{1}{2} = 3 + \frac{1}{2} = 3.5 \, \text{gallons}
\]
Now, multiply the number of gallons by the cost per gallon:
\[
3.5 \times 4.50 = 15.75 \, \text{dollars}
\]
So, Alex spent $15.75 on soda.

### Step 2: Calculate the cost of pizza
Alex purchased 8 pizzas at $16.49 each. Multiply the number of pizzas by the cost per pizza:
\[
8 \times 16.49 = 131.92 \, \text{dollars}
\]
So, Alex spent $131.92 on pizza.

### Step 3: Calculate the total cost for pizza and soda
Now, add the amounts spent on pizza and soda:
\[
15.75 + 131.92 = 147.67 \, \text{dollars}
\]

### Final Answer:
Alex spent **$147.67** on pizza and soda.
