The area of a rectangle is the product of its length and width:

(7 yds)(3 yds) = 21 square yds.

We must convert this to square feet.  Note that 1 sq yd = 27 sq ft.

Thus, (21 sq yd) times (27 sq ft  /  1 sq yd)  = 21(27) sq ft.  Finish this by multiplying 21 and 27 together.  Be sure to include the units of measurement.

21 square feet. Area equals width x lengths. 7*3=21

Lastima Nelson, Inc. is recruiting a new Chief Financial Officer (CFO). The recruiting budget is $44,000. Lastima has spent $10,
Musya8 [376]
The budget is $44000

Total spent so far is $10000 + $8500 = $18500

The amount left to spend = 44000 - 18500 = $25500

$25500 is the maximum 6% commission that Lastima Nelson Inc. can spend and stays within the budget

Let the maximum price of the home be x
This value of x will be the 100% before the 6% commission is calculated of it.

6% of x is 25500
1% of x is 25500 ÷ 6 = $4250
100% of x is 4250 × 100 = $425,000

So, the maximum value of the home is $425,000
