Answer:
4 blu-rays
Step-by-step explanation:
*Note: I'm rounding up to full dollars to make this easier. You will get the same answer, whether you round up or not.
First, get rid of the shipping cost from the budget.
$150 - $10 = <u>$140 left for blu-rays</u>
Then divide $140 by $30, which is the price for a single blu-ray to get the number of blu-rays Chris can get.
$140 ÷ $30 ≈ 4.6 repeating. You can't have a fraction of a movie, so Chris can get 4 blu-rays
Let's set up a proportion.
16/x= 80/100
16*5=80
x*5=100
x=20
Final answer: 20 questions total

Answer:
= 1 5/16
[/tex] 1 \frac{5}{16}[/tex]
Step-by-step explanation:
![\frac{8}{5} (2x + 13) - 3 = 22](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B5%7D%20%282x%20%2B%2013%29%20-%203%20%3D%2022)
Expand
![\frac{16}{5} x + \frac{104}{5} - 3 = 22 \\ \frac{16}{5} x + \frac{89}{5} = 2](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%7D%7B5%7D%20x%20%2B%20%20%5Cfrac%7B104%7D%7B5%7D%20%20-%203%20%3D%2022%20%5C%5C%20%20%5Cfrac%7B16%7D%7B5%7D%20x%20%2B%20%20%5Cfrac%7B89%7D%7B5%7D%20%20%3D%202)
Collect like terms and simplify
![\frac{16}{5} x = 22 - \frac{89}{5} \\ \frac{16}{5} x = \frac{21}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%7D%7B5%7D%20x%20%3D%2022%20-%20%20%5Cfrac%7B89%7D%7B5%7D%20%20%5C%5C%20%20%5Cfrac%7B16%7D%7B5%7D%20x%20%3D%20%20%5Cfrac%7B21%7D%7B5%7D%20)
Cross Multiply
![80x = 105](https://tex.z-dn.net/?f=80x%20%3D%20105)
Divide both sides of the equation by 80
![\frac{80x}{80} = \frac{105}{80} \\ x = \frac{21}{16}](https://tex.z-dn.net/?f=%20%5Cfrac%7B80x%7D%7B80%7D%20%20%3D%20%20%5Cfrac%7B105%7D%7B80%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B21%7D%7B16%7D%20)
