Answer:

17

Step-by-step explanation:

Let the larger number be represented by x

Let the smaller number be represented by y

from the question, the next equations can be gotten :

x - y = 9  equation 1

x = 1 + 2y equation 2

Substitute for x in equation 1

1 + 2y - y = 9

1 + y = 9

Collect like terms

y = 9 - 1

y = 8

Substitute for y in equation 1 and solve for x (the larger number)

x - 8 = 9

x = 9 + 8

x = 17

McKenzie buys 250 shares of stock for $12 a share and pays a 2% commision. She sells the stock 3 years later for $18 a share and
Artemon [7]
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 <==
