Hi Jahlen!

So I would first identify the variables: K for Kristen C for Charlene and S for Sasha.

K = 110 + S [Kristen makes 110 more than Sasha]

C = 2(K) so 2(110 + S) [ Charlene makes Twice as much as K.

K + C + S = 2930 [ They all make together 2930]

(110 + S) + [2(110 + S) + S = 2930

110 + S + 220 + 2S +’S = 2930

330 +’3S = 2930

4S = 2600

S = 650

K= 110 + 650 =

K = 760

C = 2(K) = 2(760)

C = 1520

650 + 760 + 1520 = 2930, So it works!

I hope this helps!
