Answer:
9%
Step-by-step explanation:
Final Value-Starting value / Starting Value
100,280 - 92000 = 8280
8280/92000 = 0.09
0.09 -> % = 9% increase
<u>Your answer is 28x^2-37x+12</u>
<u>1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd</u>
28x^2-21x-16x+12
<u>2) Collect like terms</u>
28x^2+(-21-16x)+12
<u>3) Simplify</u>
28x^2-37x+12
10% on first 10k is 1,000
20% on 5k is 1,000
You owe 2,000
