Answer:
An experimental study
Step-by-step explanation:
An experimental study should be used. This will enable the energy drink manufacturer to have an experimental group and control group. Using experimental study, the effect of independent variables on the dependent variables can be determined with the amount of the drink consumed as the controlled factor.
You would need a scientific calculator for this exercise.
On your calculator you simply enter the symbol e. (Please ensure your calculator has nothing on display before this)
After pressing the e button, you press the x raised to the power of y symbol and then input 3.32, as shown below;
$80 x 0.19% = $15.2
$80 + $15.2 = $95.2
$110 - $95.2 = $14.80
The answer is: d. $14.80
Wait, so is the problem 6x + y = -39 or is it something else? Because I'm seeing two different expressions… comment back for help.
