A) S + D = 200
B) 85 S + 110 D = 18,250 we multiply A) by -85
A) -85 S -85 D = -17,000 then we add to B) and get
25 D = 1,150
Double Bed Rooms = 46
Single Bed Rooma = 154

Double Check
46 * 110 = 5,060 154 * 85 = 13,090

Answer:
The value of the total ticket sales is, 2500
Step-by-step explanation:
Let x be the total ticket sales.
As per the statement:
if 15% of the total ticket sales is $375

then;

Divide both sides by 15 we have;

multiply both sides by 100 we have;
x = 2500
Therefore, the value of the total ticket sales is, 2500
Total volume of the tank is 5000 cubic units
Volume of liquid=60%*5000=3000 cubic units
the height of the fluid will be found as follows
V=πr²h
where:
r=20/2=10 units
hence:plugging in the values and solving for h we get:
3000=π×(10²)×h
thus
h=3000/(100π)
h=9.5292966
h=9.5293 units
