The MePhone, a new smartphone, is being introduced in the Louisville area. The manufacturer plans to sell 30,000 phones during the first week and expects sales to increase by 8% each week after that find the equation, determine if its aritmetic or geometric, wk 0 is 30,000 wk 1 is 32,400 fill in the rest of the table

Y = 30000 + 0.08x*30000
Factor out 30000:
Eq: Y = 30000(1+0.08x).
Y = The # of phones sold.
x = The # of wks required to sell the phones.
When x = 0, Y=30000(1+0.08*0))= 30,000.
When x = 1, Y=30000(1+0.08*1)= 32,400.
When n = 2, Y=30000(1+0.08*2)= 34,800.
(x,y).
(0,30000)
(1,32400)
(2,34800).
Add as many wks as required.
