the cost of 5 similar digital cameras and 3 similar video cameras is $3213 each video camera costs 4 times as much as each digital camera. john buys a digital camera and a video camera. how much does he pay?

I was wondering how to do it with bar graphs?

v = 4d

5d+3v = 3213
5d+3(4d) = 3213
17d = 3213
d = 189
v = 756

so, d+v = ?

its 5 grade math, can you make it more understanding

The price of 4 digital = one video.

5 digital + 3 video = 3213

Substitute 4d for v in second equation and solve for d.

5 digital + 3(4 digital) = 3213

Insert that value into the first equation and solve for v. Check by inserting both values into the second equation. Since John buys one of each, add the two values.

Does that make it clearer?

To Anya:

I’m in fourth, and okay, so you know.
Can you stop bragging now?

To Anya: Oh, stop bragging. It hurts other people’s feelings

This is 5 th grade math make it understandable

To find out how much John pays for the digital camera and the video camera, we need to determine the cost of each camera separately.

Let's assign variables to the cost of each digital camera and video camera. We'll represent the cost of a digital camera as 'D' and the cost of a video camera as 'V'.

According to the given information, we know that the cost of 5 similar digital cameras and 3 similar video cameras is $3213. We can write this as the following equation:

5D + 3V = 3213 ...(equation 1)

It is also mentioned that each video camera costs 4 times as much as each digital camera. We can express this relationship as:

V = 4D ...(equation 2)

To solve this system of equations, we can substitute the value of V from equation 2 into equation 1:

5D + 3(4D) = 3213

Simplifying the equation:

5D + 12D = 3213
17D = 3213
D = 3213/17
D ≈ 189

Now, we can substitute this value of D back into equation 2 to find V:

V = 4(189)
V = 756

Therefore, a digital camera costs approximately $189, and a video camera costs approximately $756.

Since John buys one digital camera and one video camera, we can find the total cost he pays by adding the individual costs together:

Total cost = Cost of digital camera + Cost of video camera
Total cost = $189 + $756
Total cost = $945

Therefore, John pays $945 for a digital camera and a video camera.

So, the answer is 945 dollars. I knew that and I am in 5th grade.
