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 one at very bottom was my final answer
Let's begin by putting together some equations:
Seth has charges $39 and then $13 per hour. Since "hour" is our variable, let's write that as $13h where h = the number of hours.
Seth = 39 + 13h, $39 plus $13 times the number of hours
Malcolm charges $55 and then $11 per hour. So:
Malcolm = 55 + 11h, $55 plus $11 times the number of hours
Our goal is to find out how many hours both have to work before they charge the same amount. So let's set our Seth and Malcolm equations equal to one another.
39 + 13h = 55 + 11h, because we want to solve for h to see the number of hours.
First let's subtract 39 from each side:
(39 + 13h) - 39 = (55 + 11h) - 39
13h = 16 + 11h
Now let's subtract 11h from each side:
(13h) - 11h = (16 + 11h) - 11h
2h = 16
Simplify and solve for h by dividing each side by two:
(2h)/2 = (16)/2
h = 8
So Malcolm and Seth would have to work for 8 hours before both earn the same amount. After 8 hours, Seth would earn more than Malcolm. Before 8 hours, Malcolm would earn more than Seth.
Option A: 6x^2+75x+200 is the correct answer
Step-by-step explanation:
The profit is obtained by subtracting the cost from the revenue.
Given
The Profit function will be obtained by subtracting the cost function from the revenue function
So,
Hence,
