Answer:
Step-by-step explanation:
We want to write an exponential function that goes through the points (0, 20) and (6, 1280).
The standard exponential function is given by:
The point (0, 20) tells us that <em>y</em> = 20 when <em>x</em> = 0. Hence:
Simplify:
So, our exponential function is now:
Next, the point (6, 1280) tells us that <em>y</em> = 1280 when <em>x</em> = 6. Thus:
Solve for <em>b</em>. Divide both sides by 20:
Therefore:
Hence, our function is:

Ok so first, you add $8.50, $10.25, and $2.25 to get the total bill of $21. Since 3 people are splitting the bill equally, divide $21 by 3 to get $7. Hope this is helpful!
Yes it is, any decimal after the number one will be bigger than one
