Ernie earned $121.50 more than kaylin. tria earned $35 less than 3 times the amount kaylin earned. ernie, tria, and kaylin earned $579 in all. how much did tria earn? $98.50 $220.00 $260.50 $330.50

C) $260.50

Step-by-step explanation:

Let "x" be the amount earned by Erine.

Let "y" be the amount earned by Kaylin.

Let "z" be the amount earned by Tria.

Now let's form the equations.

x = y + 121.50   (1)

z = 3y - 35  (2)

x + y + z = 579  (3)

Now plug in x = y + 121.50, in the third equation.

y + 121.50 + y + z = 579

2y + z = 457.50

From the second equation 3y - z = 35

2y + z = 457.50

3y - z = 35

5y = 492.5

Dividing both sides by 5, we get

y = 98.50

Now let's find how much Tria earned.

z = 3*98.5 - 35

z = $260.50
