Suppose that a worker in country a can make either 10 ipods or 5 tablets each year. country a? has 100 workers. suppose a worker in country b can make elther 2 ipods or 10 tablets each year. country b has 200 workers. a bundle of goods that country b could potentially make would be:
multiple choice
200 ipods, 1,500 tablets
400 ipods, 2,000 tablets
300 ipods, 450 tablets
400 pods, 1 tablet

300 iPods, 450 tablets

Step-by-step explanation:

Data:

Country A has 100 workers. 1 worker can make either 10 iPods or 5 tablets each year.

Country B has 200 workers. 1 worker can make either 2 iPods or 10 tablets each year.

For this problem we only need to use Country B data. Let's calculate the maximum number of iPods or tablets they can make in 1 year:

Total iPods = 2 x 200 =  400 (if they only make iPods)

Total tablets = 10 x 200 = 2000 (if they only make tablets)

By calculating this we can discard option B and option D. Because it has the maximum number of iPods (year limit) and some tablets. And this is not possible for the workers.

Now let's analyze option A:

For 200 iPods we need: 200 / 2 workers = 100 workers

For 1500 tablets we need: 1500 / 10 workers = 150 workers

100 workers + 150 workers = 250 workers ≥ 200 workers

It is proved that option A is impossible, because it exceeds the workers that  Country B has.

Now let's analyze option C:

For 300 iPods we need: 300 / 2 workers = 150 workers

For 450 tablets we need: 450 / 10 workers = 45 workers

150 workers + 45 workers = 195 workers ≤ 200 workers

It is proved that option C is the only viable one for Country B.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
