452 m2

476 m2

524 m2

548 m2

whats the answer plz

Step-by-step explanation:

Given

See attachment

Required

The uncovered area

First, calculate the area of the rectangle

From the attachment

and

So:

The area of the triangle is:

From the attachment

So:

The uncovered area is:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
