If the goal of this question is to solve for x than the correct answer is 20. Hope this helped.
39.58 and this is because the radius is half of the diameter so the diameter can be though of as 2r. The formula is C= 2pi r
Answer:
D
Step-by-step explanation:
The amount of drinks is a linear function of the number of drinks. The maximum amount that can be purchased is 100 soft drinks.
Let
amount of drinks
number of drinks
For drinks not more than 50

For drinks more than 50.

For a purchase of $85, it means that:

So, we solve for x in both equations.

Divide by 0.7

By comparing both values:



Hence, the maximum amount that can be purchased is 100
