Answer:
(a)k=44.245
(b)39820.50 PHP
Step-by-step explanation:
<u>Part A</u>
Let the number of PHP =y
Let the number of USD =x
The number of Philippine Pesos(y) received is directly proportional to the number of US Dollars(x) to be exchanged.
The equation of proportion is: y=kx
If 550 USD can be converted into 24,334.75 PHP.
- x=550
- y=24,334.75
Substitution into y=kx gives:
The constant of proportionality k=44.245
<u>Part B</u>
The equation connecting y and x then becomes:
y=44.245x
If x=900 USD
Then:
y=44.245 X 900
y= 39820.50
Therefore, given that you have 900 USD to convert. You will receive 39820.50 PHP
