Answer:
Step-by-step explanation:
Let the number of cars be x and buses be y
<u>Then we have below inequalities as per given:</u>
- 5x + 32y ≤ 1310
- x + y ≤ 135
It is easy to notice that cars occupy 6 times less area than buses but cost of parking is 3 times less. So we would need maximum number of cars and minimum number of buses to maximize income
<u>Let's assume there are 135 cars and buses, then from the second inequality:</u>
<u>Substitute it in the first one:</u>
- 5(135 - y) + 32y ≤ 1310
- 675 - 5y + 32y ≤ 1310
- 27y ≤ 1310 - 675
- 27y ≤ 635
- y ≤ 635/27
- y≤ 23.5
The greatest number of buses is 23
Option D. 23 is correct
Answer:
24 cups
Step-by-step explanation:
Answer:
The answer is: " 9 mi. "
Step-by-step explanation:
1 week = 7 days
Total exercise: 30 mi/ wk.
3 mi * 7 = 21 mi. / wk running.
How many miles per week biking?
Assuming that her exercise is strictly: 1) running; and 2) biking:
30 mi - 21 mi. = 9 mi.

Hello!</h2>
The answer is:
The cost of the watch is $19.39.
<h2>
Why?</h2>
To solve the problem, we can create a linear equation using the given information about the starting balance and the ending balance.
We know that the starting balance was $515.50, and then, after writing a check to buy the watch, the balance was $496.11, so, writing the function we have:
Hence, we have that the cost of the watch is $19.39.
Have a nice day!
