Currency Conversion and Proportionality

The video tutorial explains how to exchange US dollars for Philippine pesos using direct proportionality. It introduces variables for US dollars (u) and Philippine pesos (p), and demonstrates the direct variation equation p = k * u, where k is the constant of proportionality. The tutorial calculates k using given values and applies it to convert 950 US dollars to Philippine pesos, concluding with a helpful note.

What is the relationship between U.S. dollars and Philippine pesos in this context?

• They are directly proportional.

• They are inversely proportional.

• They are unrelated.

• They are equal in value.

In the context of direct variation, what does the variable 'k' represent?

• The total amount of pesos.

• The total amount of dollars.

• The constant of proportionality.

• The exchange rate.

How do you calculate the constant of proportionality 'k'?

• By adding the pesos and dollars.

• By dividing the pesos by the dollars.

• By multiplying the pesos by the dollars.

• By subtracting the dollars from the pesos.

What is the value of the constant of proportionality 'k' in this example?

• 550

• 24.439.8

• 44.436

• 950

If you have 950 U.S. dollars, how many Philippine pesos can you get using the constant of proportionality?

• 44,436

• 42,214.2

• 24,439.8

What equation is used to convert U.S. dollars to Philippine pesos?

• p = u / k

• p = k * u

• p = k - u

• p = k + u

What is the first step in using the constant of proportionality to convert currency?

• Divide the constant by the amount of dollars.

• Add the constant to the amount of dollars.

• Multiply the constant by the amount of dollars.

• Subtract the constant from the amount of dollars.

• 24,439.8

What is the purpose of finding the constant of proportionality in currency conversion?

• To establish a fixed rate for conversion.

• To find the difference between pesos and dollars.

• To determine the total amount of pesos.

• To calculate the total amount of dollars.

What is the significance of the final example in the video?

• It shows a different method of conversion.

• It confirms the accuracy of the constant of proportionality.

• It introduces a new currency.

• It changes the constant of proportionality.
