Answer: C=[ (10) x (19.60)÷ (8)]
Step-by-step explanation:
Given , The cost of 8 books = $ 19.60
Then, By UNITARY method , the cost of one book = ( Cost of 8 books ) ÷ ( 8)
i.e. The cost of one book = ($19.60) ÷ ( 8) ...(i)
Now , cost of 10 books = (10) x (Cost of one book)
From (i) , we get
Cost of 10 books =$[ (10) x (19.60)÷ (8)]
Let C be the cost of 10 books ( in dollars) .
So , the equation would help determine the cost of 10 :
C=[ (10) x (19.60)÷ (8)]
Answer:
BE=AD
Step-by-step explanation:
Q = The Ammount Of Cranberry Juice
(q+4)*4.50=q*6.30+4*3.60
4.5*q+18=6.30*q+14.4
6.30*q-4.5*q=18-14.4
1.8*q=3.6
q=3.6/1.8
It Would Be 2 Quarts Of Cranberry Juice
