<span>For me,
It would be a rational decision if the first worker was more than twice as productive as the second worker.</span>
This can happen in real life, for example 2 workers are hired to do the same type of job but one worker graduated with honors, the company can give a higher pay to the worker with honors compared with the other one who graduated.
It is up to the company on how much they would pay their workers as long as it is above the minimum wage. Though there might be hurt feelings among the workers if they each knew how much they are paid for, it is also better for the company to inform workers that they are paid this certain amount because of the following reasons (graduated w/ honors).
To work out this question, you need to think of what ratio there is of white cars to yellow cars.
You know that there are 9 times as many white cars as yellow cars.
This means for every white car you have, you have 9 yellow. 1:9.
So for every 10 cars we have (9+1) we have 1 white car and 9 yellow cars.
Next, we take the total number of cars (40) and divide it by the total number of white+yellow cars we have (10)
40 / 10 = 4.
Now, we times 4 by the numbers in the ratio.
1 x 4 = 4.
9 x 4 = 36.
We can double check this by doing 36 / 4 = 9.
We know that Rafael counted 4 white cars.

Answer:
Total cooking time = 20t + 15
The expression 15t + 20 is wrong.
Step-by-step explanation:
weight of chicken = t lbs
cook time per lb = 20 minutes
This means that:
1 lb weight requires a cooking time of 20 minutes
1 lb = 20 minutes
∴ t lbs = 20 × t = 20t minutes.
We were also told that each chicken required an extra cooking time of 15 minutes, in addition to the total cooking time due to the weight. Therefore, the total cooking time is calculated thus:
Total cooking time = cooking time due to weight + 15 minutes
Total cooking time = 20t + 15
Hence the expression 15t + 20 is wrong, due to the explanation given above.
