To find the answer to this question, we first have to find out how much of the mix of the combined blueberries and cherries is.
To do so, simply add the two amounts together.
5.75+4.5=10.25
Now, just divide 10.25 by .06 to get the amount of sundaes they can make.
10.25/.06=170.8 or 170
They can make 170 sundaes
Hope this helps!
