Respuesta :

It would be (14•18) + 14•b & 14•(18+b)
Okay so for each bracelet we know that the 18 beads PLUS the unknown (b) amount of glass beads, TIMES the 14 friends, we can write out the equation.

14 · 18 + b

Now, using 4 for b and using the order of operations (PEMDAS), let's solve the equation.

14 · 18 + 4
256

That answer does seem reasonable, but we only added 4 beads, instead of 4 beads PER BRACELET. So, we can fix our equation by putting 18 + b in parentheses. 

The answer is 14 · (18 + b) :)
