The polleys want to put in a swimming pool next summer. they need to save $6,000 over 12 months in order to achieve this goal. they set aside the same amount each month and after 7 months discovered they have saved $3,100. the polleys know that they must adjust their plan in order to meet their goal, so they come up with the following options:
option a: save the original amount each month but put the pool in one month later than originally planned.
option b: increase savings each month by $100 from their original plan.
which of the following statements is true?
a.
only option a will allow them to meet their goal.
b.
only option b will allow them to meet their goal.
c.
either option a or b will allow them to meet their goal.
d.
neither option a nor option b will allow them to meet their goal.

D    Neither option A nor option B will allow them to meet their goal.

Step-by-step explanation:

Option D is the correct answer.

Step-by-step explanation:

The Polley's need $6000 in 12 months so technically this is $500 savings per month.

After 7 months they found they have $3100 but the exact amount they should have in 7 months was $3500. So, they are$400 short. Now for the remaining 5 months, they must save = 6000-3100 =$2900 which means they must save each month 2900/5 =$580

Now checking option A :

Save the original amount each month but put the pool in one month later than originally planned.

The original amount was $500, so in 5 months they will save 500*5 =$2500. And will be short of $400 as in total they need $2900. So, this cannot be possible in next months time.

Checking option B : Increase savings each month by $100 from their original plan

This becomes $600 each month for the next 5 months. This makes a total amount of $3000. This amount exceeds their goal.

So, option D.) Neither option A nor option B will allow them to meet their goal.- is the right answer.

i got 142 as my answer
