A distrubutor wants to make 1,000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is
Cerrena [4.2K]

Answer:

<em>He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call

x = pounds of trail mix 5% raisins

y = pounds of trail mix 20% raisins

The distributor wants to make 1,000 pounds of trail mix, thus:

x + y = 1,000     [1]

The mix must be 8% raisings as a combination of x and y, thus:

5x + 20y = 8*1,000 = 8,000

Dividing by 5:

x + 4y = 1,600     [2]

Subtracting [2] and [1]:

4y - y = 1,600 - 1,000

Operating:

3y = 600

y = 200

From [1]

x = 1,000 - y = 1,000 - 200

x = 800

He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins

How much more will $28,000 earn in interest than $16,000 if both are
WINSTONCH [101]

Answer:

Final answer is $12696.

Step-by-step explanation:

Given that initial amount P = $28000

Interest rate r = 5.8% = 0.058

Time = 1 year

Then future value is given by :

A=P\left(1+r\right)^t

A=28000\left(1+0.058\right)^1=29624

Similarly calculate future value for 2nd case:

Given that initial amount P = $16000

Interest rate r = 5.8% = 0.058

Time = 1 year

Then future value is given by :

A=P\left(1+\frac{r}{n}\right)^{n\left(t\right)}

A=16000\left(1+0.058\right)^1=16928

then difference = 29624 - 16928 = 12696

Hence final answer is $12696.
