Determine whether the two expressions are equivalent. If so, tell what property is applied.
If not, explain why.
18. 18 x 17 18
19. 8 + 1.2 = 1.2 + 8
20. 10 = (8 - 4) = (10 - 8) dived by 4

the bolded word " farsighted" could be replaced with visionary.

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

answer is  

a.

p = 78
