Hello,
You don't know (a-b)(a+b)=a²-b²?

Step-by-step explanation:
Since the shelves are 75.5cm long, the total length she would be needing is 75.5cm × 6 = 453cm
Now, the length of the wood she is using is 180cm, to get enough length to make the shelves, we would need to divide 453cm by 180cm which gives a value of around 2.51
This is approximately equal to 3 when rounded up to the nearest whole number.
Cookies: $13.40 divided by 2.5 = $5.36
Crackers: $24.75 divided by 4.5 = $5.50
Therefore, Cookies are less.
