I hope I did this correctly! If not I'm sorry about the inconvenience.

Answer 2

Well. She has 10 and needs 15 of travopost. She has 3 and needs 12 of latanoprost.

10 + T = 15
10 + T - 10 = 15 - 10
T = 5
3 + L =12
3 + L - 3 = 12 - 3
L = 9

She needs to order 5 boxes of travopost and 9 boxes of latanoprost.
