1. On Day 2, Raj makes 70 more bagels than on Day 1. What is the opportunity cost of producing 70 more bagels? [tex]$\square$[/tex]

2. On Day 3, Raj makes 50 more croissants than on Day 2. What is the opportunity cost of producing 50 more croissants? [tex]$\square$[/tex]



Answer :

Let's break down the opportunity cost for each production change day by day, using the given schedule.

### Opportunity Cost of Producing 70 More Bagels on Day 2:
On Day 1:
- Doughnuts: 600
- Bagels: 70
- Croissants: 50

On Day 2:
- Doughnuts: 500
- Bagels: 140
- Croissants: 50

Raj increased the production of bagels by 70 (from 70 on Day 1 to 140 on Day 2). We need to identify the opportunity cost of this increase in terms of the other products, focusing on doughnuts, since the number of croissants remains constant.

To find the opportunity cost:
- The number of doughnuts produced on Day 1 was 600.
- The number of doughnuts produced on Day 2 dropped to 500.

The difference in doughnut production from Day 1 to Day 2 is:
[tex]\[ 600 - 500 = 100 \][/tex]
Therefore, the opportunity cost of producing 70 more bagels on Day 2 is 100 doughnuts.

### Opportunity Cost of Producing 50 More Croissants on Day 3:
On Day 2:
- Doughnuts: 500
- Bagels: 140
- Croissants: 50

On Day 3:
- Doughnuts: 500
- Bagels: 70
- Croissants: 100

Raj increased the production of croissants by 50 (from 50 on Day 2 to 100 on Day 3). We need to identify the opportunity cost of this increase in terms of the other products, focusing on doughnuts, since the number of bagels significantly dropped.

To find the opportunity cost:
- The number of doughnuts produced on Day 2 was 500.
- The number of doughnuts produced on Day 3 remained 500.

There is no difference in doughnut production from Day 2 to Day 3:
[tex]\[ 500 - 500 = 0 \][/tex]
Therefore, the opportunity cost of producing 50 more croissants on Day 3 is 0 doughnuts.

### Summary:
- For producing 70 more bagels on Day 2, the opportunity cost is 100 doughnuts.
- For producing 50 more croissants on Day 3, the opportunity cost is 0 doughnuts.
