Samuel and jason spend 3/4 of their combined earnings from wednesday to buy a gift. how much do they spend? is there enough left over from wednesday's earnings to buy a card that costs $3.25? explain.
earnings:
samuel - (12.5×0.40)
jason - (7.1×0.40)

they spend $ 5.88 to buy a gift but there is not enough money left to buy a card of $3.25

Step-by-step explanation:

The earnings form Wednesday of Samuel and Jason are:

   Samuel earnings = 12.5x0.40 = $5

   Jason earnings = 7.1x0.40 = $ 2.84

The combined earnings form Wednesday are:

   Combined earnings = Samuel earnings + Jason earnings

   Combined earnings= $5 + $ 2.84 = $ 7.84

The spended earnings are:

    Spended earnings = combined earnings x ¾

    Spended earnings = 7.84 x ¾ = $ 5.88

The left over is:

    Left over = combined earnings – spended earnings

    Left over = 7.84 – 5.88 = $ 1.96

So, they spend $ 5.88 to buy a gift but there is not enough money left to buy a card of $3.25

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
