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

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

answer: 1+1

step-by-step explanation: 1+1 is at least 2
