Answer:
for Mike: 0.2 tables,for Sandy: 1/3 tables
Step-by-step explanation:
To calculate the opportunity cost, we can simply divide the cost of what is given up by what is gained.
=> The opportunity cost for chair can be calculated by dividing the total numbers of table made in 1 month by the numbers of chairs made in 1 month.
- In 1 month, Mike can make 4 tables or 20 chairs, so that the Opportunity cost of 1 chair is: OC of 1 chair for Mike = 4/20 = 0.2 table
- In 1 month, Sandy can make 6 tables or 18 chairs, so that the Opportunity cost of 1 chair is: OC of 1 chair for Sandy = 6/18 = 1/3 table
