8x - 5x = 34 + 2
3x = 36
3x/3 = 36/3
x = 12

Answer:
- <em>1. Morty's total cost for the items he purchased was </em><u><em>$210</em></u>
- <em>2. Morty's revenue from the sale of the items was </em><u><em>$547</em></u>
- <em>3. Morty's Total profit was </em><u><em>$337</em></u>
<em />
Explanation:
The complete question is:
<em>Morty buys and sells computer parts. He bought two monitors for $25 each and later sold them for $88 each. He bought four cases for $15 each and later sold them for $24 each. He bought five memory modules for $20 each and later sold them for $55 each.</em>
<em />
- <em>Morty's total cost for the items he purchased was</em>
- <em>Morty's revenue from the sale of the items was</em>
- <em>Morty's Total profit was </em>
<em />
<h2><em>Solution</em></h2>
<em />
<u><em>1. Morty's total cost for the items he purchased was</em></u>
<em />
Build a table with the number of parts and their costs:
Component Amout Unit cost Total cost
$ $
Monitors 2 25 50
Cases 4 15 60
Memory 5 20 100
Total cost = $50 + $60 + $100 = $210
<u><em>2. Morty's revenue from the sale of the items was</em></u>
<em />
Build a table with the number of parts and their selling prices:
Component Amout Unit price Total cost
$ $
Monitors 2 88 176
Cases 4 24 96
Memory 5 55 275
Total revenue: $176 + $96 + $275 = $547
<u><em>3. Morty's Total profit was </em></u>
<em />
The total profit is the total revenue less the total cost: $547 - $210 = $337.
Answer:
a. d = 1500 - 300t. b. after 2 hours and after 4 hours
Step-by-step explanation:
a. Since Jamie hikes up the mountain at a rate of 300 ft/hr, and the mountain is 1500 ft high, his distance, d from the peak of the mountain at any given time,t is given by
d = 1500 - 300t.
b.If Jamie distance d = 900 ft, then the equation becomes,
900 = 1500 - 300t
900 - 1500 = -300t
-600 = -300t
t = -600/-300
t = 2 hours
The equation d = 1500 - 300t. also models his distance from the peak of the mountain if he hikes down at a constant rate of 300 ft/hr
At d = 900 ft, the equation becomes
900 = 1500 - 300t
900 - 1500 = -300t
-600 = -300t
t = -600/-300
t = 2 hours
So, on his hike down the mountain, it takes him another 2 hours to be 900 ft from the peak of the mountain.
So, he is at 900 ft on his hike down after his start of hiking up the mountain at time t = (2 + 2) hours = 4 hours. Since it takes 2 hours to climb to the peak of he mountain and another 2 hours to climb down 900 ft from the peak of the mountain.
