To find out how much money Mike spent on stamps, we can calculate the total cost of each type of stamp separately and then add those amounts together.
1. Calculate the cost of the 20 stamps that cost $0.45 each:
\[
20 \text{ stamps} \times 0.45 \text{ dollars/stamp} = 9.00 \text{ dollars}
\]
2. Calculate the cost of the 15 stamps that cost $0.32 each:
\[
15 \text{ stamps} \times 0.32 \text{ dollars/stamp} = 4.80 \text{ dollars}
\]
3. Now add the two amounts together:
\[
9.00 \text{ dollars} + 4.80 \text{ dollars} = 13.80 \text{ dollars}
\]
Therefore, Mike spent a total of **$13.80**.
