Cost of 12 copies that Melissa needs to pay = $0.66
Then
Cost of 1 copy that Melissa needs to pay = (66/12) dollars
= 11/2 dollars
Now
The cost of 56 copies that Melissa has to pay =(11/2) * 56
= 11 * 28 dollars
= 308 dollars
So Melissa needs to pay $308 for 56 copies.<span>I hope the procedure is clear enough for you to

Answer:
(a) or (b) but i think its (b)
Step-by-step explanation:
Answer:
-y^(2)+x+y
Step-by-step explanation:
A) 1
B) 10/3
C) 6
D) 18/5
So only C is bigger than 4
--------------------------------------------------
Define x :
--------------------------------------------------
Let Cheryl be x years old.
Cheryl = x
Lisa = x + 6
--------------------------------------------------
In two years time:
--------------------------------------------------
Cheryl = x + 2
Lisa = x + 8
--------------------------------------------------
Lisa will be twice as old as Cheryl :
--------------------------------------------------
x + 8 = 2(x + 2)
--------------------------------------------------
Solve x :
--------------------------------------------------
x + 8 = 2(x + 2)
x + 8 = 2x + 4
x = 4
--------------------------------------------------
Find their age :
--------------------------------------------------
Cheryl = x = 4
Lisa = x + 6 = 4 + 6 = 10
--------------------------------------------------
Answer: Lisa is 10 years old now.
