Step-by-step explanation:

To find the area of a rectangle you have to multiply the base times the height. So you would do 4 x 2 to equal 8.

Hope this helps :)

answer: options?

step-by-step explanation:

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
