all i did was i multiplied 5.02 by 30

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

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
