Answer:
Kim bought 12 sandwiches.
Step-by-step explanation:
In order to find the amount of sandwiches that Kim bought we have to take the total amount she spent on the restaurant (35) subtract the amount she spent on the large potato salad (5) and divide the result by the price of each sandwich (2.5) So we have:
amount spent on sandwiches = 35 - 5 = 30
number of sandwiches = 30/2.5 = 12
Kim bought 12 sandwiches.
There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
