2 answers:
Answer:
store 1 has the better deal.
Step-by-step explanation:
Two stores offer differently prices sales for the same paper towels.
Store 1 sells 15 paper towel rolls at the price = $3.60
The price of one paper towel roll = = $4.1666 ≈ $4.17
Store 2 sells 18 paper towel rolls at the price = $3.80
The price of one paper towel roll = = 4.7368 ≈ $4.74
Store 1 sells at $4.17 per paper towel and store 2 sells each towel at $4.74.
Therefore store 1 has the better deal.

Answer:
For linear equations we use:
p=mx+b ------ (1)
Now we have the following coordinates:
(x1,p1)= (1000,280) and (x2, p2)=(5000,400)
First we need slope (m)
m=
=
Now we will plug the value of m in the first equation
=>
=> b = 250
Now plug into p=mx+b using only m=0.03 and b=250
When the unit price is $440, we can plug in 440 in for p;
=>
=>
=> x = 6333 refrigerators
The lowest price at which a refrigerator will be marketed, we can find this by plugging x = 0 in p=mx+b.
=> p = $250
