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. The Greens must adjust their plan in order to meet their goal, so they came up with the following options: Option A: Stay with saving the original amount each month but put the addition on one month later than originally planned. Option B: Increase the amount of money they save each month by $120 from their original plan.
Answer:
So he should go with option B
Step-by-step explanation:
The Greens will need to save to achieve his goal = $10,620
After one year if they have saved $6120.00 this means they save
6120 ÷ 12 = $510 per month
This means after 18 months they save
510 × 18 = $9,180 only. this is not enough for his goal.
so if he increases the amount of money by adding $120 from their original plan he could achieve his goal
= 510 + 120 = $630 per month
= 630 × 18 months = $11,340
So he should go with option B.
