$76.51
Step-by-step explanation:
I found how much the calculator cost on clearance first. Then I found the sales tax and added them together.
For the surface of rectangle to be minimum the the dimensions must be equal. Let the length=width=height=x cm
thus the volume will be:
x×x×x=28
x³=28
x=∛28
x=2√7 cm
thus the dimensions are such that length=width=height=2√7
2m+-m=7
3m-8=7
Then add 8 to both sides of the equation.
simplify.
Divide both sides of the equation with the same term.
simplify.
m=5
