Answer:
(a^8)/(b^9)
Step-by-step explanation:
Two rules of exponents come into play.
(a^b)/(a^c) = a^(b-c)
a^-b = 1/a^b
__
Applying the first rule, we have ...
(a^3)/(a^-5) × (b^-2)/(b^7) = a^(3 -(-5)) × b^(-2 -7) = a^8 × b^-9
Applying the second rule gives the simplified form ...
= (a^8)/(b^9)
If the original price tag of the video game is $128, to get its discounted price at 15%, that means what Leiff paid for was (100-15) = 85% of the original price.
So, the price of the video game then becomes
(0.85 x 128) = $108.80.
Since Leiff has to pay an additional 5.3% of the new price, that's (100 + 5.3) = 105.3% of the new price which is
(1.053 x 108.8) = $114.57
Adding the shipping fee for the videogame,
114.57 + 4.75 = $119.32
Thus, the total price is <span>$119.32</span>
Answer:
Total trade discount on 30 boxes = $201.555
Step-by-step explanation:
1 box = $14.93
And a trade discount of 45% is allowed on a single box,
Therefore, the discount on one $14.93 box will be
45% × $14.93 = $6.7185
So, if there are now 30 boxes, the trade discount on all 30 boxes will be
30 × (trade discount on one box) = 30 × ($6.7185) = $201.555
Hope this helps!
