To find out how many pieces of chewing gum David can buy, we first need to determine how much money he has left after buying the shirt.
1. David starts with $90.
2. He buys a shirt for $25.
Calculating the remaining amount:
\[
90 - 25 = 65
\]
Now, David has $65 remaining. The price of one piece of chewing gum is $3.
To find the maximum number of pieces of chewing gum he can buy, we divide the remaining amount by the price of one piece of gum:
\[
\frac{65}{3} \approx 21.67
\]
Since he can only buy whole pieces of gum, we take the floor of this number:
\[
\text{Maximum pieces of chewing gum} = 21
\]
Thus, the maximum number of pieces of chewing gum David can buy is **21**.
