PLEASE HELP ASAP Please The height of the tide of the ocean is measured along a cliff. The water level oscillates between 2 feet at low tide and 16 feet at high tide. Low tide occurs at 8 a. m. and high tide is at 2 p. m. At t = 0, the height of the water is 9 feet.

answer: group b.

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
