Question

What is the answer to this?

Answer 1

Answers:

Biggest = 100 inches

Smallest = 31 inches

=======================================================

Work Shown:

Replace d with 132 to get,

Tmax = 3d/4 + 1

Tmax = 3*132/4 + 1

Tmax = 396/4 + 1

Tmax = 99 + 1

Tmax = 100

The biggest size they should buy is a 100 inch tv.

Do the same for the minimum size equation.

Tmin = d/4 - 2

Tmin = 132/4 - 2

Tmin = 33 - 2

Tmin = 31

The smallest tv they should buy is a 31 inch tv.
