Margareta is selling freshly baked cookies at 50¢ a cookie, and $2.00 for a pack of 5 cookies. Nathan is selling freshly picked strawberries for $2.00 per pound, and $10.00 for 5 pounds. Who has a proportional relationship between cost and item? Margareta
Nathan
Both Margareta and Nathan
Neither of them

 Nathan has a proportional relationship between cost and item

Step-by-step explanation:

Using Margareta's statement we will say that if you buy 1 cookie you pay 50 cents and if you by 5 cookies you will pay $2

To find out how much you will pay for one cookie by using the 5 cookies $2 statement we will divide  2 by 5

2/5 = 0.4   which means you pay 40 cents for 1 cookie and that is not equivalent to paying 50 cents per cookie so Margereta method is not proportional.

Nathan sells freshly picked strawberries for $2 per pound and $10 for 5 pounds.  Now we want to know how much you have to pay per pound if you were to buy 5 pounds to $10 .

Divide 10 by 5 to find out how much you will pay per pound.

10/5 = 2    

So Nathan is selling his strawberries at a proportional rate which is $2 per pound.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

1) is right
