Answer: Option A
Step-by-step explanation:
Ron paid $1500 every month, with a bonus of $100 for every tractor that he sells.
For how this is worded, we can think that he is paid a fixed amount of $1500 and another $100 for each tractor that he sold, so if he sold 2 tractors, he will get $1500 + 2*$100 = $1700
The equation that models this is:
Y = $100*x + $1500
where x is the number of tractors that he sells, so the correct option is A.
