Misha and her cousin Darius made muffins for the Clark family reunion. Misha made 17 more muffins than Darius. Dark is made 56 m
VMariaS [17]

Answer:

Number of muffins per plate.  

Step-by-step explanation:

We are given the following in the question:

Let x be the number of muffins made by Dark

Then, number of muffins made by Misha =

x + 17

For x  = 56

Muffins made by Dark = x = 56

Muffins made by Misha =

x + 17 = 56 + 17 = 73

Total number of muffins =

56 + 73 = 129

Total  number of plates = 12

Number of muffins on each plate =

=\dfrac{\text{Total number of muffins}}{\text{Total number of plates}}=\dfrac{129}{12} = 10.75\approx 11

Thus, there were approximately 11 muffins on each plate.

Thus, the unit of this problem is number of muffins per plate.
