The area of the garden 10 ft•50 ft= 500 sq ft
Answer:
3 machine
Step-by-step explanation:
It is given that 6 machine each working at the same rate can complete the work in 12 days
We the has to complete in 8 days
Let we need x extra machine to complete the work in 8 days
So total number of machines =x+6
Now according to man work day equation 



x=3 machine
250 shares for $ 12 per share......250 * 12 = 3000
plus the 2% commission......3000(1.02) = 3060...so the commission is $ 60
she then sells her stock (250 shares) for $ 18 a share....
250 * 18 = 4500
plus the 1% commission....4500(1.01) = 4545...so the commission is $ 45
net proceeds is the amount received by the seller after all costs and expenses are deducted...
expenses : 3000 + 60 + 45 = 3105
revenue : 4500
net proceeds = 4500 - 3105 = $ 1395 <==
