Which situation could best be represented by this linear equation?
24x + 38y = 520

(C.)If x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520.

Step-by-step explanation:

Hi,  to answer this question we have to analyze the equation given:

24x + 38y = 520

In general, prices of thing doesn't change, they are constant values. Values that can vary are the quantities sold.

For example for the term 24x, since 24 is a constant it can be the price of a bracelet, and x the number of bracelets sold.

Adding both products is equal to the total sales.

So, the correct option is C.

If x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520.

Step-by-step explanation:

I just took the quiz on edge

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)
