Let x be the number of movies rented
Let y be the number of video games rented
(5x+2y=26)4
- 3x+8y=53
20x+8y=104
-3x+8y=53
-----------------
17x =51
x=51/17
x=3
5x+2y=26
5(3)+2y=26
2y=26-15
y=11/2
y=5.5
Therefore, the movies cost $3 and the video games cost $5.5
Hope I helped :)

Let's set up an inequality. t will equal the amount of hours.
123.80 [greater than or equal to] 47 + 9.60t
After isolating t, your answer is t less than or equal to 8. So they can rent the meeting room for at most 8 hours.

(4,8)
Answer:
152
Step-by-step explanation:
Given the function :
C(x)=−15x+2304
The least Number of items, x that can be produced so that average cost does not exceed $33
C(x) = less than or equal to 33
33 = - 15x + 2304
33 - 2304 = - 15x
-2271 = - 15x
x = 2271 / 15
x = 151. 4
Hence, the least number of items that can be produced is 152
