Answer:
Bs = 72
Bm = 96
Ml = 120
Step-by-step explanation:
We have that to total 288 boxes of cupcakes (1/4) are small (Bs), (1/3) are medium (Bm) and the rest (x) are large (Bl), so we must find (x) and the total of each of the boxes needed each month .
[tex]x=1-\frac{1}{4}-\frac{1}{3}\\ 12x=12-3-4\\12x=12-7=5\\x=\frac{5}{12}[/tex]
knowing that Bs=T/4, Bm=T/3 and Bl=5T/12: T=288
Bs = 288/4 = 72
Bm = 288/3 = 96
Bl = 5*288/12 = 120
