So b is the correct answer
Answer:
1.6667
Step-by-step explanation:
If the number of downloads of the standard version is x, and the high quality is x, 2.1*x+4.1*y=2761 (not 1010 due to that this is multiplied by 2.1 and 4.1, therefore representing the total amount of megabytes) In addition, there are 1010 total downloads, and it's either 2.1 MB or 4.1 MB, so x+y=1010.
We have
2.1x+4.1y=2761
x+y=1010
Multiplying the second equation by -2.1 and adding it to the first equation, we get 2y=2761-1010*2.1=640 and by dividing both sides by 2 we get y=320 downloads of the high quality version
What we know... Parents car is $8,000 --- Volvo costs $8,000 x 3 3/4
3 3/4 is the same as 3.75
$8,000 x 3.75 = $30,000
Matt Kaminsky's Volvo costs $30,000
