Answer:
Step-by-step explanation:
Hello!
To compare different prices of several brands of a product the best is to express the price for the same quantities of product.
Since the three options are original in 300g, 450g and 600g, I'll express all prices on a base of 100g of product. You can use simple rule of three for this:
Option 1
300g cost $3.89
100g cost 
Option 2
450g cost $ 4.77
100g cost 
Option 3
600g cost $ 6.59
100g cost 
So:
Option 1: $1.296/ 100g
Option 2: $1.06/100g
Option 3: $1.098/100g
The cheapest option is number 2
I hope this helps!
Answer:
6 x 14 = 84
84 x 2(since there are two small rectangles) = 168
22 x 6 = 132
132 x 2 = 264
264 x 2(since there are two of the same shape) = 528
22 x 14 = 308
308 x 2(since there are two of the same shape) = 616
Now we add up all the areas:
168 + 528 + 616 = 1312 square cm is your answer.
