Question

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?

Answer 1

1450 - 400= 1050
1050÷150=7
so alex sold 7 cars at Keith Palmer Ford last week

Answer 2

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.
