Step-by-step explanation:
The revenue is the profit times the number of computers sold
R(t) = P(t) * N(t)
= (13t^2-25t+600) * ( 5t+106)
We want the revenue in 2010 which is 5 years from 2005 so t = 5
R(5) = (13* 5^2-25*5+600) * ( 5*5+106)
= (13 *25 - 125+600)*(25+106)
= (325-125+600) * ( 25+106)
(325-125+600) * ( 25+106)
800* 131
104800
Hi!
To solve this inequality, we have to isolate x on one side. Whatever we do to the equation we have to do it on both sides.
1.30x + 5.20 ≤ 18.20
Subtract 5.20 from both sides.
1.30x + 5.20 - 5.20 ≤ 18.20 - 5.20
1.30x ≤ 13
Divide by 1.30 on both sides.
1.30x/1.30 ≤ 13/1.30
x ≤ 10
