Jon and lexi are playing a marble game. according to their rules, 6 points are awarded for each red marble collected and 2 points are awarded for each blue marble collected. which expression represents jon's total score if he has r red marbles and b blue marbles? (1 point)

9x

your answer   is c

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
