Multi-step problems with addition and subtraction 1
A bakery has \(1500\) fresh rolls in the morning. It sells \(900\) rolls before noon and then bakes \(400\) more.
Caio writes:
Step 1: \(1500-900=600\)
Step 2: \(600+400=1000\)
Explain what the \(600\) represents. How many rolls are in the bakery after the additional baking?
Hints
- Identify the two quantities used in the first subtraction.
- Sold rolls are no longer in the bakery.
- The second step adds the rolls baked later.
Solution
1. The calculation \(1500-900=600\) subtracts the rolls sold from the starting amount.
2. Therefore, \(600\) represents the rolls remaining after the morning sales.
3. Adding the newly baked rolls gives \(600+400=1000\) rolls.
Answer
The \(600\) represents the rolls left after the morning sales. After baking more, the bakery has \(1000\) rolls.
