Tim has $156 saved up and he wants to buy books which cost $12 each linear equation Y equals -12 X +156 represents the situation where a wire represents the mount of money Tim has left an X represents the number of books purchased what does the X intercept in the situation represent

my answer is$ 12

step-by-step explanation:

because 15 -2=12

answer: (3,11) is your answer.

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
