The total cost of Francis's purchases is $75.44.
The total cost of the purchase is the sum of the costs of the video games, taxes and the DVDs. Total cost increases by each of these items.
Total cost = tax + cost of the 2 video games + cost of the dvd
Total cost of the video games = 2 x 29.95 = $59.90
Total sales tax paid = 8% x ($59.90 + $9.95)
= 0.08 x $69.85
= $5.59
Total cost of the purchase = $59.90 + $9.95 + $5.59 = $75.44

The amount of the final solution is 4 + 1 = 5 quarts.
The amount of alcohol in the final solution is 5 * 0.36 = 1.8 quarts.
The concentration of alcohol in the 4 quarts of alcohol solution that was added is:
Y = -3x + 4 this line has slope = -3
perpendicular lines, slope is opposite and reciprocal
so slope of perpendicular line is 1/3
passing thru (6,-2)
y = mx + b
b = y - mx
b = -2 - (1/3)(6)
b = -2 - 2
b = -4
equation
y = 1/3(x) - 4
hope it helps
You would write it as (1/10^12)
any negative exponent does the same thing
ex: x^-1 turns into (1/x^1)
