30(.50) - 8 = 15 - 8 = $7 profit
15 - 6 = $9 profit
(1/4) / 4 = 1/16 each day
(4-5i)(-5-5i) =
- ( 4 - 5i)(5 + 5i) =

Very nice, guest !!!!!

He can bring 7 people (including himself)
We have
6800 (1.025)^x
____________ where x is the number of years
x
f (x) = (x + 1)^3 (x - 2)(x - 5) = x^5 - 4 x^4 - 8 x^3 + 10 x^2 + 23 x + 10
He receives 44 cents in change
1 quarter 1 dime 1 nickel 4 cents = 7 coins
Let T be the total amount he earns....so....
T - (1/9)T - (1/2)T - (1/4)T = 20 common denominator = 36
(36/36)T - (4/36)T - (18/36)T - ( 9/36)T = 20
(5/36)T = 20
T = 20 ( 36/5) = $144
