Answer: 3000=250x+750
Step-by-step explanation: In this equation, the 3000 is the amount she wants, so that is on the left; the 750 is added, because she doesn't get 750 every time she sells a car, it is static. the 250 is multiplied by x, where x is the number of cars she sells. for every car she sells, she earns $250. (to get the goal, she would need to sell 9 more cars, don't know if that's needed)
