Consuela earns a salary of $40,000 per year plus a commission of $1000 for each car she sells right and solve an equation that shows the number of cars consuela must sell in order to make 60,000 in one year

The equasion she would use would be 60,000 = 1000x + 40,000

this would means 1,000 times a number plus the 40,000 shes already getting equals 60,000

Well she automatically makes 40,000 a year. lets say x is the amount of cars she sells. and she gets 1,000 for each sold. so if she sells 2 cars she would get 2 * 1,000. 3 cars would be 3 * 1,000. but we just want to say x cars so we use x * 1,000.
so she makes 40,000 plus her commission which is x * 1,000. so if the amount she makes is represented by y then:
y = 40,000 + (x * 1,000)

if she wants to make 60,000 in a year then y = 60,000. substitute that into our equation and get
60,000 = 40,000 + (x * 1,000)
20,000 = x * 1,000
x = 20.

so she would have to sell 20 cars
