Alex sells cars at keith palmer ford. he earns $400 a week plus$150 per car he sells. if he earned $1450 last week, how many cars did he sell?

I’m going to set up an equation to solve this.

150x+400=1450 where x equals the number of cars he sold last week.

150x+400=1450
First you would subtract 400 on both sides of the equal sign.

150x=1050
Then you would divide both sides by 150 to get
x=7.

Alex sold 7 cars last week.
