Step-by-step explanation:
a. y = 2 + 4.3(-6)
y= 2- 25.8
y= -23.8 or y= -24
b. y= (9-3)2
18-6=12
c. y= 3.5-2
y= 1.5
d. y= 5(-2) - 4
y= -10-4
y= -14
Answer:

<em>100 grams</em>
4,900 grams = 4,900 grams
5 kilograms = 5,000 grams
<em>5,000 - 4,900 = 100</em>
c is the answer
$270
Price after markup was 1.20($250) = $300
Price after discounting: (1.00 - 0.10)($300) = $270
