At the beginning of the month, Evan had $24 in his account at the school bookstore. Use a variable to represent the unknown quantity in

each transaction below and write an equation to represent it. Then

represent each transaction on a number line. What is the unknown

quantity in each case?

answer: ouch. thats difficult

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

3.73 * 10^7 is the anser for ttm ur welcome < 3

step-by-step explanation:

16 would be your answer
