Answer:
48 ways
Step-by-step explanation:
Let me take a guess
S₁_₁₅ = (1+15)*7 + 8 = 120
There are 48 combinations of distinct digits from 1 to 15 to make 20
120-20=100
So every 20 has a corresponding 100
I wish I got it right, otherwise report it.
Somewhere in the 600, 500 or 700 maybe even 800?
Answer:800
75% = 0.75
600/0.75 = x/1
Cross multiply:
0.75x = 600
Divide 0.75 to both sides:
x = 800
So the full does is 800mg.
