Sam salmon is interested in purchasing stock. he wants to determine the costs.

The answers for the empty boxes are, in order:

$97.50, $1722.50; $67.86, $1198.80; $21.96, $387.96; $91.62, $1618.60; $79.32, $1401.30

Step-by-step explanation:

To fill in the first column, the amount of commission, we multiply the total for each stock by the commission rate, 6%.  6% = 6/100 = 0.06; this means we multiply each by 0.06:

0.06(1625) = 97.50

0.06(1131) = 67.86

0.06(366) = 21.96

0.06(1527) = 91.62

0.06(1322) = 79.32

Next we add each amount of commission to the total for the stock:

1625+97.50 = 1722.50

1131+67.86 = 1198.80

366+21.96 = 387.96

1527+91.62 = 1618.60

1322+79.32 = 1401.30

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
