Answer:
Step-by-step explanation:
42 × 48
(40 + 2) × (40 + 8)
40 × (40 + 2) = (40 × 40) + (40 × 2) = 1600 + 80 = 1680
8 × (40 + 2) = (40 × 8) + (2 × 8) = 320 + 16 = 336
Then 1680 + 336 = 2016

Answer:
Step-by-step explanation:
Two sheets will cost: $27
The value of the first sheet will be $18, and since the other sheet is half off it will be half of the original value: 18 * 0.5 = 9.
Then you add the values together: 18 + 9 = 27.
Six sheets will cost: $81
For every sheet that is the original value there is a sheet that is half off. So since there are six sheets, 3 of the sheets will be $18 and three of them will be $9. We already know that 18+9=27, so just multiply that value by 3.
27*3= 81
Better deal: The second example
In the second example sheets are 30% off. 30% of 18 is $6. Subtract that value from 18 and you will get $12. In the second example one sheet is $12.
If we multiply that value by 2, we will get $24.
In the first example, two sheets costs $27, while in the second example two sheets cost $24. Since the cost is less for the second example, the second example is the better deal.
