Answer:
The maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.
Step-by-step explanation:
Given : A total of 1,000 BTUs are needed to cool a space. If 2.5 BTUs are needed to cool 1 cubic foot of space.
To find : What is the maximum volume of space that 1,000 BTUs will cool?
Solution :
Applying unitary method,
2.5 BTU are needed to cool 1 cubic foot of space.
So, 1 BTU are needed to cool
cubic foot of space.
Then,1000 BTU are needed to cool
cubic foot of space.
i.e. 1000 BTU are needed to cool 400 cubic foot of space.
Therefore, the maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.

Step-by-step explanation:
I know because I know that how
Answer:
$300
Step-by-step explanation:
original price = $250
the profit= 15%
ok now let the cost price of article be ₹ x
x + 15% of x = 250
1.15x = 250 => 115x ÷ 100 = 250
115x = 25000 => x = 25000 ÷ 115
x = 5000/ 23
cost price of article = ₹5000/ 23
required profit = 38%
= 38% of 5000/ 23 = 0.38 × 5000/ 23
= 1900/ 23
the required will be selling price to gain about 38%
= cost price + required profit which is
= (5000/ 23) + (1900/ 23)))
= 6900/ 23 = $300
Answer: now its required selling price = $300
