pls slove this pls​

Answer 1

Answer:

x = .05 * 600 = 30

y + z = .95 * 600 = 570

So far so good. Now let’s figure out how many men are split in y and z. Per the question, it’s half in y and half in z, so:

y = .5 * 570 = 285

z = .5 * 570 = 285

Now for the final equation, total number of earrings. If x is 1 earring and y is 2 we get:

1*x + 2*y + 0*z = total

Plugging in values gives us:

1*30 + 2*285 + 0*285 = 30 + 570 = 600

So we have 600 total earrings being worn in this club.

Now for the final equation, total number of earrings. If x is 1 earring and y is 2 we get:

1*x + 2*y + 0*z = total

Plugging in values gives us:

1*30 + 2*285 + 0*285 = 30 + 570 = 600

So we have 600 total earrings being worn in this club.
