ANYONE GOOD AT MATHS simple question, I can't work it out?

Basically I am on accutane, and picked up my prescription today and I think they have given me the wrong amount of the drug. Can anyone help me by working it out? I am just blinded by these numbers:

I need to be on 50mg of accutane for 6 weeks. That's 50mg daily. So I need 50mg each day for 45 days.

I was given

2 boxes of 10mg accutane, each containing 30 tablets

3 boxes of 20mg accutane, each containing 30 tablets

I am to dose myself, ie it's my job to make sure I take 2 x 20mg tablets and 1 x 10mg tablet each today to receive 50mg in total daily.

I think I should have been given one more box of 20mg tablets for my dosage to work, but I can't make sense of it. Will someone please work this out before I call the pharmacy?

Thanks so much!

    For 45 days you need 2 big tablets each day for 45x2 = 90 big tablets.

    For 45 days you need 1 small tablet each day for 45x1 = 45 small tablets.

    You were given 3 boxes of 30 for a total of 3x30 = 90 big tablets. This is the correct number.

    You were given 2 boxes of 30 for a total of 2x30 = 60 small tablets. This is more than the 45 you need.

    So, you won't run short.
