masha68 [24]

Answer: 5942

<u>Step-by-step explanation:</u>

Clue 4 states exactly two of the digits = 1, 4, or 9

Clue 1 leaves us with the following combinations:

1, 9, 2, 8

1, 9, 3, 7 eliminate by clue 5

4, 9, 2, 5

1, 4, 7, 8

Clue 5 directs us to the following order for 1,9,2,8

2 __ __ 1 --> 2981 or 2891 eliminate by clue 2

9 __ __ 8 --> 9128 or 9218 eliminate by clue 6

9 __ __ 2 --> 9182 or 9812 eliminate by clue 6

Clue 5 directs us to the following order for 4,9,2,5

5 __ __ 2 --> 5492 or 5942 eliminate 5492 by clue 2

9 __ __ 2 --> 9452 or 9542 eliminate by clue 3

Clue 5 directs us to the following order for 1,4,7,8

4 __ __ 1 --> 4781 or 4871 eliminate by clue 2

The only combination not eliminated is 5-9-4-2, which satisfies all six clues.

1) 5 + 9 + 4 + 2 = 20

2) 5 > 4

3) 9 - 2 > 5

4) 4 & 9 but not 1 are included

5) 5 + 2 = 7, which is a prime number

6) 2 < 5, 9, 4

Naomi buys a new computer for $840. She is considering two payment plans that require weekly payments. Which plan will play for

Lera25 [3.4K]

Answer:

The plan that will play the computer faster is Plan A $180 down $60/wk payments

Step-by-step explanation:

Plan A.

As the computer has a value of $840 and Naomi pays $180 initially, she has a balance of $660, so $\frac{\$ 660}{\$60/wk}=11weeks$ .

Plan b.

As the computer has a value of $840 and Naomi pays $0 initially, she has a balance of $840, so $\frac{\$ 840}{\$70/wk}=12weeks$ .

Hence, Plan B delays 1 week more than Plan A, so if Naomi chooses plan A will pay the computer Faster.
