Answer:
It is more efficient to use order of operations because with the distributive property, you would have to multiply four times and add once (5 things to do), whereas with order of operations, you have to add twice and multiply twice (4 things to do).
Step-by-step explanation:
So we know that 2 workers can make 2 chairs in 2 days. Therefore if we use that same proportion, we will find that 8 workers can make 8 chairs in 2 days.
But the question is asking for 20 days, so we must multiply this by 10.
So, when we multiply 8 by 10, we find that in 20 days, 8 workers can make 80 chairs.
