Step-by-step explanation:

The Greens want to put an addition on their house 18 months from now.

They will need to save $10,620 in order to achieve this goal.

They set aside the same amount each month, and after a year discover they have saved $6,120.

Part A:

They saved $6120 in 12 months.

So, each month they saved = dollars

Now, if they save $510 for 19 months, they will save total = dollars

This amount is less than what the family needs to save.

Part B:

Increasing the amount of money they save each month by $120,

=>

Now after 18 months, they would have saved;

dollars
