Answer:
Step-by-step explanation:
the product is a result of multiplication....so lets multiply
x^2 (x^4 + x^2 - 1) =
x^6 + x^4 - x^2
ok...his mistakes are occurring because he is multiplying the exponents when he is supposed to be adding them.
exponent rule : x^a * x^b = x^(a + b)
S + l. = 34
11s + 21l= 514
-11s - 11l= -374
11s + 21l = 514
10l = 140
l = 20 long sleeve shirts
s + 20 = 34
s = 14 short sleet shirts
Original price = $33,750
Marked down price = $29,700
Amount of decrease = $33,750 - $29,700
= $3050
What you are trying to find is the percentage of "amount of decrease" as compared to "original price" ("original price" will be your 100%).
Amount of decrease ÷ original price = $3050 ÷ $33,750 <This will be your ratio>
To find percentage decrease, $3050 ÷ $33,750 × 100 = 9.04% (rounded off to 3 significant places)
Hope this helps! :)
