Someone please help! 15+ points, no links. <3 (Ill give brainliest to correct answer) Which of the following best describes the expression 9(x + 7)?
Select one:
a. The sum of constant factors 9 and x + 7
b. The product of constant factors 9 and x + 7
c. The product of a constant factor 9 and a 2-term factor x + 7
d. The sum of a constant factor 9 and a 2-term factor x + 7

i think the amount would be $140.62

you divide them and then you get the answer i took this class this year

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

2x=70  

x=70/2

x=35

thats the answer
