Step-by-step explanation:
This is a word problem that we must translate to mathematical expression before we can solve.
let the individual saving be the first letters of the names
Jada= J
Lin= L
Elena= E
1. Jada saved $20 less than Lin
J=L-20
2. Lin saved 3 times as much money as Elena
L= 3E
3. Hence Elena saved
E
Together they saved $120.
hence
(L-20)+3E+E= 120
L-20+3E+E= 120
collecting like terms we hav
L+4E=120+20
L+4E= 140
but we know that L= 3E
3E+4E= 140
7E= 140
divide both sides by 7 we have
E= 140/7
E= $20
This means Elena saves $70
also L= 3E
L= 3*20
L= $60
this means that Lean saved $60
also J=L-20
J= 60-20
J= $40
This means that Jada saved $40
