C. If you have to add on a number it is nonproportional
Answer:
$216
Step-by-step explanation:
This question does not involve interest, so all we need to do is to divide the total of payments ($10,368) by the number of payments (48):
$10,368
--------------- = $216/month
48
First you need to work out how much string is needed -
256 pieces needed x 40cm each:
256 x 40 = 10240cm
Then, convert to metres (100cm = 1m)
10240 / 100 = 102.4m
Then, you work out how many balls are needed:
30 can fit into 102.4 3 times with .41m to spare. So, you need three balls of string, PLUS another one to cover the 41cm
So to conclude: 4 balls of string are needed.
It's 7:10. There are 14 gray and 20 black, which simplifies to 7:10.
