Here is a price list of products at the neighborhood grocery store:
David has 49 shekels. He buys some bread at the store. How much money does he have left?
To solve this problem, we'll follow these steps:
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.
Calculating, we get:
.
Therefore, after purchasing bread, David has shekels left.
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Look for the product name in the right column, then read across to find its price in the left column. Bread is in the second row, so its price is 9 shekels.
You would add up all the costs first, then subtract that total from 49. But this problem only mentions bread, so we only subtract 9.
When you spend money, you have less than before! Subtraction shows money going away. Adding would mean David somehow gained money by shopping.
Ask yourself: Should David have less money after buying something? Yes! Since 40 < 49, this makes sense. Also verify: ✓
A negative answer would mean David doesn't have enough money to buy the bread. But since 49 > 9, he can afford it and will have money left over.
