It takes Betty 2 h to bake a cake and 7 h to knit a sweater. What is her opportunity cost of 1 cake in terms of knitted sweaters? (Enter the number only and express it in decimal form by rounding to the second decimal place.)
As per the question Betty takes 2hours to bake 1 cake
Then, he should be taking 1hours to bake 1/2 cake
Betty takes 7hours to knit 1 sweater
he should be taking 1hours to knit 1/7 sweater
Though both the products are made by Betty
So at 1 hours he can produce either 1/2 cake or 1/7 sweater
Thus 1/2 cake = 1/7 sweater
1cake = (1/7)x 2 sweater
1cake = 2/7 sweater
1cake = 0.2857 sweater (by rounding to two decimal places)
1cake = 0.29 sweater
The opportunity cost of producing 1cake = 0.29 sweater
