Let initial no. of magnets = 12m.

1/4 of total : 3m

Remainder after Pierre : 12m - 3m - 6

                                        = 9m - 6

2/3 of remainder : 2/3 * (9m - 6)

                            =  6m - 4

Remainder after Kelsey : 9m - 6 - (6m - 4) - 2

                                      = 3m - 4

    Since 12 magnets remain, 3m - 4 = 12

                                               3m = 16

                                             12m = 16 + 4

                                                     = 64

  Kelsey took 6m-4+2

                     =6m-2

                    6m = 12m/2 = 32

                   6m-2 = 32-2 = 30

Guess #1: 3 science fiction novels and 1 mystery novel

Find the number of books:

3 + 1 = 4

Find the total cost in dollars:

(9 × 3) + (2 × 1) = 27 + 2 = 29

The guess is incorrect. Try another guess.

Guess #2: 2 science fiction novels and 2 mystery novels

Find the number of books:

2 + 2 = 4

Find the total cost in dollars:

(9 × 2) + (2 × 2) = 18 + 4 = 22

The guess is incorrect. Try another guess.

Guess #3: 1 science fiction novel and 3 mystery novels

Find the number of books:

1 + 3 = 4

Find the total cost in dollars:

(9 × 1) + (2 × 3) = 9 + 6 = 15

The guess is correct. Uncle Porter bought 1 science fiction novel and 3 mystery novels.

I haven't done anything so far. Because it's so hard

Let the amount clayden has be X

Given : 

sum of money clayden and jayden have=$784

So x+ amount jayden has =$784

Amount jayden has=$784-x

Clayden spent \( {1 \over 6}\frac{}{}\) =\({1 \over 6}\frac{}{}\)* X

So amount left with clayden=x-\(x = {x \over 6}{}^{}\frac{}{}\)

Amount left with clayden =\( {5x \over 6}\frac{}{}\)

Jayden spends $124 

So amount left with jayden = $784-$124-x

So amount left with jayden=$660-x

Given :both have same amount left 

Hence - 660-x=\( {5x \over 6}\frac{}{}\)

660*6-6x=5x

660*6=11x

60*6=x

360=x

Amount clayden has =$360
