AFC = FC / Quantity printed 

<span>So given she prints 1,000 posters: AFC = 250.00/1000 = $0.25 </span>
<span>Given she prints 2,000 posters: AFC = 250.00/2000 = $0.125 </span>
<span>Given she prints 10,000 posters: AFC = 250.00/2000 = $0.025 </span>

<span>ATC = TC / Quantity printed </span>

<span>where TC = FC + Variable C * Quantity printed </span>

<span>If she prints 1000: TC = 250 + 2000*1000 = 2,000,250 </span>
<span>ATC = 2,000,250/1000 = 2000.25 </span>

<span>If she prints 2000: TC = 250 + 1600*2000 = 3,200,250 </span>
<span>ATC = 3,200,250/2000 = 1600.125 </span>

<span>If she prints 10000: TC = 250 + 1600*2000 + 1000*8000 ($1000 for each additional poster after 2000) = 11,200,250 </span>
<span>ATC = 11,200,250/10000 = 1120.025</span>

Suppose a city with population 500,000 has been growing at a rate of ​7% per year. If this rate​ continues, find the population
krok68 [10]

Answer:

2,070,281

Step-by-step explanation:

let x = number of years

let y = population

Given:

  • initial population = 500000
  • rate of increase = 7%

y = 500000 × 1.07^x

when x = 21:

y = 500000 × 1.07^(21) = 2070281.187... = 2,070,281

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

5(x + 2) = 6x + 3x - 14

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Addition] Combine like terms:                                                                        5(x + 2) = 9x - 14
  2. [Distributive Property] Distribute 5:                                                                 5x + 10 = 9x - 14
  3. [Subtraction Property of Equality] Subtract 9x on both sides:                      -4x + 10 = -14
  4. [Subtraction Property of Equality] Subtract 10 on both sides:                       -4x = -24
  5. [Division Property of Equality] Divide -4 on both sides:                                x = 6
