Calculate Remaining Money: 49 Shekels Minus Bread Purchase

To solve this problem, we'll follow these steps:

• Identify the given information: David starts with 49 shekels.
• Determine the cost of the bread: It costs 9 shekels.
• Use subtraction to find the remaining money.

Now, let's work through each step:
Step 1: David has 49 shekels initially.
Step 2: The price of the bread is 9 shekels.
Step 3: Subtract the cost of the bread from the total money.

$\text{Remaining Money} = 49 - 9$

Calculating, we get:

$\text{Remaining Money} = 40$.

Therefore, after purchasing bread, David has $40$ shekels left.
