Lynette wants to buy heart-shaped cookies for her classmates. And order of 4 cookies cost $2.00. if she wants to buy a large batch at the same price, which equation best represents the number of cookies purchased, x, and the cost, y? a. y=2x
b. y=4c
c. y=1/2x
d. y=1/4x

what level of math? also i don't need to be paid if i can you.

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

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.

you are having disney spells!
