Answer:
The answer is 358.01
Step-by-step explanation:
Given:

Now, to solve first we crack the power notation then multiply and then do the addition:

(The value of
is 10 and the value of
is 1.)


.
Therefore, the answer is 358.01 .
B) C=0.23m+34.99
because you get you base price definitely and extra minute price can be removed if you don't use more than 100
Area= (length)(width)
divide by (length) on both sides.
(width)= (area)/(length).
Your best bet is treating area, length, and width as numbers. You can plug in numbers and take them out in the end. Hope this helps!
