product at an electronics store cost less if purchased online than in the store the chart shows the store price online

Answer 1

The subject of this question is Business. The student is asking about the price difference between purchasing a product online versus in a physical store.

Step-by-step explanation:

The subject of this question is Business. The student is asking about the price difference between purchasing a product online versus in a physical store.

To answer the question, we need to compare the prices listed in the chart for the same product both online and in-store.

For example, if the online price is $100 and the in-store price is $120, we can conclude that the product costs less if purchased online.

Answer 2

Given the following prices:

In-Store Price Online Price

$50.00 $45.00

$75.00 $67.50

$100.00 $90.00

To determine if the online price vary directly with the in-store price, let's find the constant of proportionality.

Let y = online price

Let x = In-store price

Where y varies directly as x, we have:

y = kx

45 = 50k

`\begin{gathered} (45)/(50)=(50k)/(50) \\ \\ 0.9=k \end{gathered}`

Since constant of proportionality, k = 0.9, let's determine if there is a direct variation using the second and third prices on the list.

y = kx

y = 0.9(75) = 67.5

y = kx

y = 0.9(100) = 90

`k=(45)/(50)=(67.5)/(75)=(90)/(100)=0.9`

Therefore, we can say that the online price varies directly with the in-store price. This is because they have the same constant of proportionality.

ANSWER:

Yes, the online price varies directly with the in-store price.
