<u><em>ANSWER</em></u>
I believe that the amount of the instant rebate is $30. X represents the price of the bike, and 0.09 is the sales tax.
So if the bike cost $100:
0.09(100) + (100-30) = 9 + 70 = $79
Although I think I would want them to tax the bike after the instant rebate and not on the original price.
If I'm wrong about the instant rebate then it would be 1.09x-30. Hope this helps.
3) factor 3k^2-16k+5
(3k-1)(k-5)
B is the answer.
4) Factor 2x^2+x-6
(2x-3)(x+2)
B is the answer.
5) factor 9s^2-6s+4
It can't be factored so the answer is D.
6) factor 40r^2-63r+18
(8r-3)(5r-6)
So the answer is B.
I hope this helps!
Joni should have multiplied by 1,000.
Step-by-step explanation:
Mass of the box = 67 decagrams
1 decagram = 1000 centigrams
So, 67 decagrams = 67 x 1000 centigrams
= 67000 centigrams
Joni should have multiplied by 1,000.
