Answer:
The correct answer is the third choice, z = x - 1.5
Step-by-step explanation:
x is the number of tomatoes she has before making the salad.
She uses 1.5 tomato to make a salad.
That means you need to subtract 1.5 tomatoes from the original number of tomatoes, x.
The number of tomatoes after making the salad is x - 1.5
We are told that the number of tomatoes left after making the salad is z, so z musty equal x - 1.5
z = x - 1.5
The correct answer is the third choice.
