When exchanging US Dollars (USD) for Philippine Peso (PHP) the number of Philippine Pesos received is directly proportional to the number of US Dollars to be exchanged. If 1,050 USD can be converted into 37,087.05 PHP.

Find the constant of proportionality k.

k =  (If needed, round answer to 3 decimal places.)

Using the k from above find the amount of PHP given that you have 1,450 USD to convert.

you will receive  PHP (If needed, round answer to 2 decimal places.)

Answer 1

PHP = k(USD)

37087.05 = k(1,050)

k = 37087.05/1050 = 35.321

k = 35.321

PHP = 35.321USD

PHP = 35.321(1450) = 51215.45

PHP = 51,215.45 Philippine Pesos equivalent to 1450 US Dollars
