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.
