$36 because 20% of 45 is 9 and 45 - 9 is 36!
2.50$ is the better deal. If you times 0.70$ to 5 it is 3.5$ which is more expensive
Using the recursion equation, it is found that the value of the 2nd iterate is:

<h3>What is the recursive equation?</h3>
The value of the nth iteration is given by:

The initial estimate is:

Hence, the 1st iterate is given by:

The 2nd iterate is:

Thus, the fourth option is correct.

Answer:
Depends on Howe much you can drink. It varies.
Step-by-step explanation:
Answer:
-70x + 21
Step-by-step explanation:
1-8(10x-3)
-7(10x-3)
Use distributive property
-70x + 21
(This is how we learned to do it in my school)
