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.

Answers

Answer 1

Answer:

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.

Answer 2

Answer: option b. is what I would go with

If Jim =5x - 8 and LM =2x -6,which expression represents JL?

Answers

Answer:

The correct answer is A) 3x - 2

Step-by-step explanation:

In order to find this, take the value of JM and subtract the value of LM. This will give you JL.

JM - LM = JL

5x - 8 - (2x - 6) = JL

5x - 8 - 2x + 6 = JL

3x - 2 = JL
