What is it you’re asking?
You would have to divide by three and then you would get ____cal per bar
To solve this problem, you will need to set up a proportion.
Let x = the unknown cost of the books.
![\frac{1}{1.95} = \frac{6}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B1.95%7D%20%3D%20%5Cfrac%7B6%7D%7Bx%7D)
Assuming the cost of books stays constant, you can crossmultiply and solve for x.
x = 1.95(6)
x = 11.70
Six books will cost $11.70 if 1 book cost $1.95.
Answer:
![x=2\frac{2}{17}](https://tex.z-dn.net/?f=x%3D2%5Cfrac%7B2%7D%7B17%7D)
Step-by-step explanation:
Do the distributive property. ![-3x+14+20x+72=122](https://tex.z-dn.net/?f=-3x%2B14%2B20x%2B72%3D122)
Reorder the equation to make it easier to combine common terms. ![-3x+20x+14+72=122](https://tex.z-dn.net/?f=-3x%2B20x%2B14%2B72%3D122)
Combine common terms. ![17x+86=122](https://tex.z-dn.net/?f=17x%2B86%3D122)
Subtract 86 from both sides of the equation to isolate the 17x. ![17x=36](https://tex.z-dn.net/?f=17x%3D36)
Divide both sides of the equation by 17 to isolate the x.
≈
or ![x=2\frac{2}{17}](https://tex.z-dn.net/?f=x%3D2%5Cfrac%7B2%7D%7B17%7D)
