Jolie uses 1.5 tomatoes every day to prepare her salad. If x equals the number of tomatoes Jolie had before she made her salad and z equals the number of tomatoes left after the salad is made, which equation represents the number of tomatoes Jolie has after she made her salad?

x = 1.5 − z
z = 1.5 − x
z = x − 1.5
x = z − 1.3
