In the expression , which of the following is the divisor? 1/4 divided by 5/7 A) 1/4
B) 5/7
C) 7
D) 4

what graph

step-by-step explanation:

1st part is 64,000,000

2nd part 500,000

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
