The only way the expression can be factored is if a -3 is pulled out...
-3(5t+2)
14,795,000 people out of 55,000,000
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 <==
The answer is B.) x2-14x+2y
