I’m stumped at the moment. Help. Due tomorrow! #4 which group would be in control of this experiment

Controlled variables are variables that do not change, they stay constant throughout the experiment and are the same among each experimental group. So for this experiment, some controlled variables would be;

your total amount per hour would be 26.53 dollars

subtract 40 dollars from 93.06 then divide 54.06 by 2, thats your answer

hope this !
