Answer:
1.20x + 2.50 \le 20

Step-by-step explanation:

x = number of cups of yogurt

1.20x = cost of all the yogurt only

1.20x+2.50 = adding on the cost of milk

We set this expression to be less than or equal to 20.


1.20x + 2.50 \le 20

In other words, the highest 1.20x+2.50 can go is 20 since $20 is her budget.
