Answer:
- The first mistake was in not taking 18% off the iPad price. A second mistake was in using an incorrect value for the sales tax multiplier. Those two mistakes together are why the answer is incorrect.
- ($575 +0.82·2·499)·1.08875 = $1517.02
Step-by-step explanation:
iPads are 18% off on the day of purchase, so they should be charged at ...
100% -18% = 82%
of full price. The sum shown includes two iPads at $499 each, without any discount. The total price is too high by $179.64.
The tax rate is given as 8.875%, so the multiplier on price will be ...
100% +8.875% = 108.875% = 1.08875
The multiplier used by the student in the problem is 1.0875, so is too low.
_____
A correct computation could be written as ...
($575 + 2×499×0.82)×1.08875 ≈ $1517.02
Answer:
75
Step-by-step explanation:
The measure of two supplementary angles = 15:21
The angles are 15x , 21x
15x + 21x = 180 {Supplementary}
36x = 180
x = 180/36
x = 5
Smallest angle = 15 * 5 = 75
