Answer: $10,00; $15,00 and $20,00
First, let’s mark the streaming platforms as letters x, y, z:
x - Disney +
y - Netflix
z - Hulu
Each platform costs $540,00 per year, so that would be $540,00/12=$45,00 per month
Since we know that Disney + and Hulu per year cost $300,00 and all three platforms cost $540,00 per year, we can find how much does Netflix cost per year:
$540,00-$300,00 = $240,00
Per month: $240,00/12 = $20,00
Now we can write equations according to the given information:
y = 2x
x+y+z = 540,00
x+z = 300,00
We can find how much does Disney + cost per year from the first equation, since we already know the price of Netflix per year:
2x = 240,00 / : 2
x = 120,00 (per year)
Per month: $120,00/12 = $10,00
And finally, since we know that all three platforms cost $45,00 per month, we can find the price of Hulu per month:
$45,00 - $20,00 - $10,00 = $15,00
So, Netflix costs $20,00 per month, Disney + - $10,00 per month and Hulu - $15,00 per month
