Answer:
50 customers can be expected to use a shopping cart at a grocery store
Explanation:
We can create the equation 2/7 = x/350 (x representing the new number of customers).
We then can do 350/7 which equals 50.
This means that our new equation is 2/7 = 50/350.
Therefore, it is expected that fifty out of three hundred and fifty customers will be expected to use a shopping cart at a grocery store.
