Step-by-step explanation:

Given : The function [tex]C = 12x + 1500[/tex]  models the cost of consumable computer supplies for a school district. In the equation, C represents the cost   (in thousands of dollars), and x represents the number of years since 2015.  

The number of years from 2015 to 2030= [tex]t=2030-2015=15[/tex]

Substitute t= 15 in the given equation ,we get

[tex]C = 12(15) + 1500\\\\\Rightarrow\ C=180+1500\\\\\Rightharrow\ C=1680[/tex]

According to the model, the cost be for the year 2030 =  [tex]\$1,680,000[/tex]
