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
3/2x=3/4 (cross multiplied)
X=1/2 (divided both sides by 3/2)
Answer:
fiction books = 4
non fiction books = 8
non fiction books are twice fiction books.
Step-by-step explanation:
let number of fiction books be X so
non fiction books will be 12-X
12X + 25(12-X) = 248
12X -25X = -53
X = 4( fiction books)
12-4 = 8 (non fiction)
