A store's profit P varies directly with the number of items n that they purchase from a warehouse. Greg's gadgets buys 75 Wacky
vovangra [49]

Answer:

P=-2.54n.

Step-by-step explanation:

We have been given that a store's profit P varies directly with the number of items n that they purchase from a warehouse.

We know that two proportional quantities are in form y=kx, where y is directly proportional to x ad k is constant of variation.

Upon substituting our given variables, we will get:

P=kn

We are also told that Greg's gadgets buys 75 Wacky Widgets from Gadget Supply Warehouse. The store's profit for this purchase is -190.50. Let us find constant of proportionality.

-190.50=k\cdot 75

\frac{-190.50}{75}=\frac{k\cdot 75}{75}

k=-2.54

Therefore, our required equation would be P=-2.54n.

How to solve<br> (x+2) (x-3) = 0
suter [353]
Using the FOIL (First, Outside, Inner, Last) method, you multiply the two parenthesis together. First, you multiply x • x which = x^2, then outside, x • -3 = -3x. Next you multiply the inner number and variable, 2 • x = 2x, and finally the last values, 2 • -3 = -6. Then add all the values together (x^2 - 3x + 2x - 6) which equals the final answer x^2 - x - 6 :) Im not great at explaining but I hope this helps
