To buy 20 DVDs at the given rate, it would cost $200.

In the given chart, the total cost of purchasing DVDs is directly proportional to the number of DVDs purchased.

Each DVD costs $10, so to find the total cost of buying 20 DVDs, we can multiply the cost of 1 DVD by 20.

The calculation would be:

Total Cost = Cost per DVD x Number of DVDs

Total Cost = $10 x 20 = $200

So, it would cost $200 to buy 20 DVDs at this rate.

The probable question may be:

The chart shows the number of DVDs a person can purchase and the total cost.

| Number of DVDs | Total Cost |

| 1 | $10 |

| 2 | $20 |

| 3 | $30 |

| ... | ... |

| 20 | $200 |

At this rate, how much would it cost to buy 20 DVDs?
