Answer: 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.
<span>The area of a blade with rectangular shape = 1/2 * b * h where b is the base and h, the height.
Here b = 7 and height = 4
So the area of the blade = 1/2 * 7 * 4 = 14ft^2
If the are four blades the total area is the summation of individual blade.
So area = 14 + 14 + 14 + 14 = 56ft^2. Hence none of the option satisfies the answer.</span>
