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.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
