(a) how much potting soil he bought last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4....subtract 4 from both sides
28 - 4 = 2p...simplify
24 = 2p...divide both sides by 2
24/2 = p....simplify
12 = p......12 solves the equation
(d) He bought 12 lbs of potting soil last week
Answer:
$84
Step-by-step explanation:
1. If 20% is marked off, then you are selling it for 80%.
2. 455 * 80% = 364
3. Since you are finding the cost markup from 280, then 364-280=84

The answer to the question is d/15
Answer:
- 1, 1, - 3
Step-by-step explanation:
To obtain the value of f(1), we require the corresponding value of y from the graph when x = 1
From the graph
when x = 1 the value of y on the graph is - 1 ⇒ f(1) = - 1
Similarly
f(3) means what is the value of y corresponding to x = 3
From the graph when x = 3 then y = 1 ⇒ f(3) = 1
and f(- 1) = - 3
