Answer:
Joey sold 6 cars
Step-by-step explanation:
Joey earns $350 per week + $200 per car he sells
The number of cars that he sold last week is unknown, so represent it with a variable, x.
Write an equation
$350 + $200x = $1,550
Subtract $350 from both sides of this equation
$200x = $1200
Divide both sides of the equation by 200
x = 6
Joey sold 6 cars

Answer:
2a (3-4a)
Step-by-step explanation:
(2a+1)-4a(2a+1)+4a

= 2a+4a-8a²
=6a-8a²
= 2a(3-4a)
