There are a lot of possible total amount of numbers for this ratio. But any multiple of 7 will do. So just say 7, or 14, or 21.

If you choose 7, there will be 3 red marbles and 4 blue marbles. If you choose 14, there will be 6 red marbles and 8 blue marbles. If you choose 21, there will be 9 red marbles and 12 blue marbles. And the list goes on.

user100 [1]

Answer: The monthly payments for a $5,000 loan would $146.51.

Step-by-step explanation: How it looks in the TVM Solver formula:

N = 36 ( 3 (years) x 12 (monthly payments) )

I% = 3.5%

PV = $5,000

PMT = 146.51 (or 146.08 if you choose BEGIN)

FV = 0

P/Y = 12 (months)

C/Y = (12 (months)

PMT: <u>END</u> | BEGIN

The amount of money raised at a charity fundraiser is directly proportional to the number of attendees. The amount of money rais
sattari [20]

Answer:

a. M=20A

b. k=20

c. $1200

Step-by-step explanation:

<u>Direct proportions </u>

Two variables are proportional if one of them is the other by a real number. That real number is called the Constant of proportionality. If x and y are proportional, then

y=kx, where k is the constant of proportionality.

The question describes the relationship between the amount of money raised at a charity fundraiser and the number of attendees. If they have five attendees, they raise $100

a.

Let's call A the number of attendees and M the amount of money raised, and

M=kA

We know that M=100 when A=5, so

100=k(5)

This means that  

k=20

The equation for the amount raised at the charity event is

M=20A

b.

The constant of variation is k=20

c. If there are 60 attendees (A=60), then

M=(20)(60)=$1200
