Why might you want to round to the nearest hundred rather than the nearest ten

Rounding to nearest Hundred means movement of last two digits in a number, while Rounding to nearest tens means movement of only last digit.

Rounding to hundred gives a number having last two digit equal to Zero, while rounding to tens gives a number having last digit equal to 0.

For example

Rounding of 243 to nearest Hundred gives 200, while Rounding to nearest ten gives 240.

⇒If number is in hundreds or thousands or in ten Thousands that is bigger number then Rounding to Nearest hundred is better than Rounding to nearest ten.

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
