Answer:

So the fit is 2 lunch at home and 3 lunch buy

Step-by-step explanation:

Let x represents for luch at home and y represents for lunch you buy

So, we can form an equation:

18 = 1.5x + 5y

To  find how many times each work week should you make a lunch at home if you want to buy lunch as often as possible, it means y always greater than x and they are whole numbers.

We need to create a table and use the test:

x y Total cost

1 1 6.5

1 2 11.5

2 3 15

3 4 24.5

So the fit is 2 lunch at home and 3 lunch buy
