Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Sale off = 15%
Rate of sales tax = 5%
Let y be the original price of the DVD.
Amount of sales tax would be
Amount after tax would be
y + 0.05 y = 1.05y
Now, there is off of 15%, so final cost of the DVD would be
Hence, Option 'D' is correct.

1/2 of 2 is 1
1/2 of 10 is 5...
5:1
Answer:
Step-by-step explanation:
In order to determine the number of wax cubes needed to make the candle, we divide the volume of the pyramid by the volume of the cube. That is,
number of wax = volume of mold / volume of wax
The formulas are,
number of wax = (1/3)Ah / s³
Where A is the area of the base, in this case 9 cm x 9 cm which is equal to 81 cm². Substituting the known values from the given above,
number of wax = (1/3)(81 cm²)(10 cm) / (4 cm)³ = 4.21
Thus, approximate number of wax should be 4.21. If we are to round this off to the nearest whole number, we will get 5 (considering that we want rather to have excess than missing items)
