Profit and loss formulas are used to calculate the profit or loss that has been incurred by selling a particular product. They are mainly used in business and financial transactions to depict how much profit or loss a trader has incurred from any particular deal.

Let the cost which David pay for the beanie baby be x and y be the price at which Jessica bought the beanie baby

Profit formula :

Profit = Selling price (S.P.) - Cost price (C.P.)

So using the profit formula

$6 = $25 - y

$19 = y

Now using the same equation for David

-$3 = $19 - x

$22 = x.

Thus David paid $22 for the beanie baby.

Simplify the polynomial below<br><br> (a^3 + 4a^2 − 7) + (3a^3 − 2a^2 + 1)

klasskru [66]

$(a^3+4a^2-7)+(3a^3-2a^2+1)=a^3+4a^2-7+3a^3-2a^2+1\\\\=(a^3+3a^3)+(4a^2-2a^2)+(-7+1)=4a^3+2a^2-6$
