Answer:
Step-by-step explanation:
Given: Hector saved twice as much money as Sam.
Ted saved $100 more than Hector.
Gina saved $50 less than Ted.
As given, lets assume the amount of money Sam has in saving be "x".
Now, finding saving of each person given.
Writing the algebric expression of each´s saving amount.
we know, Hector saved twice as much money as Sam.
∴ Hector saving=
Also, Ted saved $100 more than Hector.
∴ Ted´s saving=

As given, Gina saved $50 less than Ted.
∴ Gina´s saving=
Opening parenthesis and solving it.
⇒ Gina´s saving=
Algebric expression of Gina´s saving=
