Question

the table shows the number of apples and the total weight of the apples.
number of apples: 2, 5, 8
weight of apples (grams): 511, 1200, 2016

1. estimate the weight of 6 apples.

Explanation:

Step1: Estimate weight per apple

First, estimate the average weight of one apple using each row, then take a reasonable average.

• For 2 apples: $\frac{511}{2} \approx 255$ grams
• For 5 apples: $\frac{1200}{5} = 240$ grams
• For 8 apples: $\frac{2016}{8} = 252$ grams

Step2: Find average apple weight

Calculate the average of the three estimated weights.
$\frac{255 + 240 + 252}{3} = \frac{747}{3} = 249$ grams, which we can round to 250 grams for estimation.

Step3: Calculate weight of 6 apples

Multiply the estimated per-apple weight by 6.
$250 \times 6 = 1500$ grams

Answer:

1500 grams
