23 +30 (15 feet each way) = 53
28 + 30 = 58
58 x 53 = 3074ft
The answer is 20 days.
After 60 people have joined there will be 460 people in the camp.
The number of days which the provisions will last will be proportional less after the 60 people have joined and will be:-
(400/460) * 23
= (20 / 23) * 23
= 20
Distance = Speed * Time
D = 25.6 * 4
D = 102.4 miles
In short, Your Final Answer would be: 102.4 miles

Answer:

Step-by-step explanation:
Given
Yearly Cost for members; 
Required
Determine the yearly cost for non members
From the question, we understand that:
<em>A non member pays $0.20 for each game;</em>
Yearly cost is then calculated as thus;
y = Amount * Number of Games
Where:
Amount = $0.2 and Number of Games = x

Convert 0.2 to fraction

Divide the numerator and the denominator by 2


<em>Hence, the yearly cost for non members is </em>

X + y = 24...y = 24 - x
3.50x + 5.00y = 97.50
3.50x + 5(24 - x) = 97.50
3.50x + 120 - 5x = 97.50
3.50x - 5x = 97.50 - 120
-1.5x = -22.50
x = -22.50/-1.5
x = 15....there were 15 ten oz boxes (x) sold
