Codes and Order of Operations
A code is as follows:
Enter a number.... then, multiply by 10, subtract 20, divide by 5, add 1...
a) If the starting number is 5, what is the last number?
b) If the output is 13, what is the input?
c) Write an algebraic expression to describe the code.
d) If the output is (K), write an algebraic expression to arrive at the original input.
