You can proceed like this,
650 kb for a pic
and 2200kb for song ( 650 + 1550)
total= 18150 kb and 16 files
so, 650 kb each in both pic and song = 16 * 650= 10400
remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5
so, a total of 5 songs and 11 pictures were sold..
hope it helped
Answer: $$5$$ movies
Step-by-step explanation: Given: A movie club, one time fee

7
2nd club,
$
0
fee, movies
=
$
12
Cost equations for each club:
club 1:
C
1
=
25
+
7
M
club 2:
C
2
=
12
M
For the clubs cost to be equal:
C
1
=
C
2
25
+
7
M
=
12
M
Subtract
7
M
from both sides:
25
=
5
M
Divide by

:
M
=

Answer:32
Step-by-step explanation:
Since they are similar, the dimensions are in the same ratio. L1 = 5, L2 = 15, so they are in a 3:1 ratio. So if V1 = 60, then W1×H1 = 60/5 = 12
W2 must also be 3×W1 and H2 3×H1, and
3×3 = 9. So take 12×9 (W×H1×9) ×15 (L2) = V2
V2 = 12×9×15 = 1620 cm^3
Let me know the right answer when you find out!
