Answer:

70

Step-by-step explanation:

You have to use ratios.  If 5 of 12 members bought water, then x of 168 members will buy water.

\frac{5}{12}  = \frac{x}{168}\\12x = 840\\x = 70

70 members will buy bottled water.

One positive number is 5 times another number. The difference between the two is 1480.
Stella [2.4K]

Hey there!

Let's create a systems of equations with x and y to find our numbers.

x=5y

x-y=1480

Let's plug our x value into the second equation.

5y=y=1480

4y=1480

y=370

Now we multiply this number by five as the first equation says to get our x.

x=1850

Our numbers are 1850 and 370.

I hope this helps!

An account earns simple interest. $1675 at 4.6% for 4 years a. Find the interest earned. $___ b. Find the balance of the account
Colt1911 [192]
A. First, divide 1675 by 100 to find 1% of it. 
1675 / 100 = 16.75 
Then, multiply 16.75 by 4.6 to get 4.6%. 
16.75 x 4.6 = 77.05 
77.05 is the interest for one year. 
Multiply it by 4 to get the interest for 4 years. 
77.05 x 4 = 308.20 
The interest earned is $308.20. 

B. Add the interest to the original balance to get the total. 
308.20 + 1675 = 1983.20 
The balance of the account is $1983.20 after 4 years. 

Hope this help!
