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.
Answer:
Step-by-step explanation:
$15 x 12Mths = $180
2 x 20 = $40 carlo gets back
$300 + $180 = $480
$480 - 40 = $440 is what carlo will spend in one year
Saves $40 from getting $2 back every time he works out
The denominator.....i dont really understand the question
Answer:
60
Step-by-step explanation:
100 x 0.4 = 40 and that is the discount so you subtract that off the price so 100 - 40 = 60
