The price of the water needs to be raised by 40% when the consumption of water reduces by 10% and the price elasticity of demand results to 25%.
<h3>What is meant by the price of elasticity of demand?</h3>
The price elasticity of demand is determined as the proportionate variation in quantity with respect to variation in the price of a good.
Given values:
Change in water consumption (fall): 10%
Price elasticity of demand: 25%
Computation of percentage change in the price of water:

Therefore, there is an increase in water price by 40%.

Answer:
h = 28/πr² or 28/(π((14/π)^⅔))
r = (14/π)^⅓
Explanation:
Given
Let r = radius, h = height of the cylinder
Volume, V =28in³
V = πr²h ----- volume of a cylinder
πr²h = 28 --- make h the subject of formula
h = 28/πr²
Area of the the cylinder is;
A = 2πr² + 2πrh
Substitute 28/πr² for h to get area in terms of radius
A = 2πr² + 2πr(28/πr²)
A = 2πr² + 56/r
Differentiate A with respect to r
dA/dr = 4πr - 56/r²
Set dA/dr to 0 (.....using the least amount of metal)
4πr - 56/r² = 0
(4πr³ - 56)/r² = 0 --- Multiply through by r²
4πr³ - 56 = 0
4πr³ = 56 --- make r the subject of formula
r³ =56/4π
r³ = 14/π
r = (14/π)^⅓
h = 28/πr²
h = 28/(π((14/π)^⅔))
Answer:
D. mass assembly
Explanation:
Mass assembly is a process used to produce very high volume products where little product variety is required.
This ultimately implies that, mass assembly is a manufacturing technique used by various industries or companies to produce standardized products (goods) in large quantities through the use of automated machineries or assembly lines from start to finish.
Hence, mass assembly avails business owners the ability or opportunity to manufacture their products in large quantities so as to enable them meet the needs or requirements of their customers for a long period of time.
Answer:
See below
Explanation:
Given the above information, the total direct labor variance is computed as;
Total direct labor variance = Standard cost - Actual cost
Standard cost = 3,600 units × 1.5 × $15 = $81,000
Actual cost = $74,400
Total direct labor variance = $81,000 - $74,400
Total direct labor variance = $6,600 Favourable
