Can someone PLEASE help me answer the last two.

if you need just tell me and i will come to the rescue.

step-by-step explanation:

total of apples - take away four

6-4 = 2

answer is 2 apples

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
