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 Widgets from Gadget Supply Warehouse. The store's profit for this purchase is -190.50. How do I write a direct variation equation on that.

.

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 , where y is directly proportional to x ad k is constant of variation.

Upon substituting our given variables, we will get:

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.

Therefore, our required equation would be .

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

i believe a. 12x≥120 is the answer
