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
X is each friend
3x + 28 > 200
3x > 172
x > $57.33
Y=-2/3x-4
Linear equation formula: y=mx+b
