Help me please ASAP 10) In 1950, the population of the United States
was 152 million people. In 1990, it was 250
million. Use a linear model to estimate the
population of the United States in 2030.
A) 326 million
B) 337 million
C) 348 million
D) 359 million
E) 360 million

the 3rd on is correct

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

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
