Final answer:
To determine how many more lobsters were caught on Day 1 than on Day 4, subtract Day 4's total from Day 1's total. To check the reasonableness, round each day's total to the nearest ten before subtracting.
Step-by-step explanation:
The question is asking how many more lobsters were harvested on day 1 than on day 4. To find the answer, we need to subtract the number of lobsters caught on day 4 from the number caught on day 1. Therefore, the calculation is 176 (day 1) - 117 (day 4), which equals 59. This means that 59 more lobsters were caught on day 1 than on day 4.
To estimate and check if our answer is reasonable, we can round the numbers to the nearest ten before subtracting, for example, 180 (day 1) - 120 (day 4) = 60. Since the estimated result is close to the exact result, our answer is reasonable.
