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:
f(86)-f(82)
Step-by-step explanation:
well f of 82 = 2 plus _ plus _ plus _ and f of 86 is 2+_+_+_ subtract them
(A) 3 (B) 4 (C) 47 (D) 59 (E) 83
these are some possible answers so the answer is b, 4
btw, 86-82 = 4 duh

Answer:
$7.50
Step-by-step explanation:
Rounded to the nearest $10, the $49.35 bill becomes $50.
We can find 10% of that amount by moving the decimal point to the left. 10% of $50 is $5.00.
Then 5% of $50 is half of 10%, so is $5/2 = $2.50.
The estimated tip of 15% is the sum of 10% and 5% of the bill, so is ...
15%($50) = 10%($50) +5%($50) = $5.00 +2.50 = $7.50
The estimated 15% tip is $7.50.
Answer:
250
Step-by-step explanation:
you have to use the fact that the big triangle and the small triangle are similar and write the proportions
we took half of the side because of ΔABD and ΔBD..
AB= (125*10)/10=125
is AB =125 then AC is duble AC= 2*125=250
The is will be -<span>11b3</span><span> - 16b</span>2<span> + </span>4b<span> + </span><span>3</span>
