You can easily take 8*10, since that equals 80, then add +2. Put parentheses around 8*10+2, then multiply that by 3. You should arrive at your answer
250 × 3 = 750

Answer:
9
Step-by-step explanation:
The possible dimensions of the larger piece of paper that could give us 1000 square inches for area are:
1×1000; 2×500; 4×250; 5×200; 8×125; 10×100; 20×50; 25×40
We want to use dimensions that will allow us to cut 8 1/2 by 11 sheets. This means that the smallest dimension needs to be larger than 8 1/2 inches; this leaves us with
10×100; 20×50; 25×40
For the first one, 10×100, we can have 1 row across the 10 inch dimension, and 100/11 = 9 columns across the other dimension. This gives us 1×9 = 9 sheets.
For the 20×50, we can have 2 rows across the 10 inch dimension and 50/11 = 4 columns; this gives us 2×4 = 8 sheets.
For the 25×40, we can have 2 rows across the 25 inch dimension (we lack half an inch of having 3) and 40/11 = 3 columns; this gives us 2×3 = 6 sheets.
The largest number of sheets was 9.
