48 bottles of water for (48 bottles is twice greater than 24 bottles)
<u>Difference:</u>
The perimeter of the square patio is the sum of its side lengths
The length of the patio is: 8x + 2
The given parameters are:
The perimeter of a square is:
So, we have:

Step-by-step explanation:
Cent: Rounding to the nearest cent or multiple of 0.01.
Dime: Rounding to the nearest 10 cents or multiple of 0.10.
Dollar: Rounding to the nearest dollar or multiples of 1.
For example, in question #21:
To round $12.3456 to the nearest cent: you must look at the hundredths place, and pay attention to the digit to its right. In this case, the digit at the hundredths place is 4, and to its right is 5. Therefore, you must round it up to 5, making it $12.3<u>5</u>.
To round $12.3456 to the nearest dime: you must look at the tenths place, and pay attention to the digit to its right. In this case, the digit at the tenths place is 3, and to its right is 4. Since 4 is less than 5, you must round 4 down to 0, making it into $12.<u>3</u>0.
To round $12.3456 to the nearest dollar: you must look at the ones place, and pay attention to the digit to its right. In this case, the digit at the ones place is 2, and to its right is 3. Since 3 is less than 5, you must round 3 down to 0, making it into $1<u>2</u>.00.
