the Answer is c. I think

44 17/20

This is super easy

Let me explain it in an understanding matter

To find average we need to add the 2 numbers then divide by the amount of numbers there is which is 2.

So the first step is to add 2 3/5 and 87 1/10

The answer to that is 89 7/10

Lastly we need to divide 89 7/10 by 2

The answer to that is 44 17/20

So your answer should be 44 17/20

(I know that's not an answer choice, But that's how i see this question)

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
