Answer:
The plant would have to work 8.33 hours
Explanation:
Initial productivity:
100 parts were produced in 1 hour
Percentage increase in productivity = 20%
New productivity:
100 + (100 × 0.2) = 100 + 20 = 120
120 parts would be produced in 1 hour
Number of hours the plant would have to work to produce 1000 parts = 1000/120 = 8.33 hours
The items that describes what happens at the equilibrium price are:
Producers supply the exact goods that consumers buy.
Consumers have enough goods, at the given price.
Producers used their resources efficiently.
Equilibrium pricing is when the items demanded match the items supplied. When this happens, the demand and good available equal each other, hence, equilibrium. The pricing is exactly where it should be for consumers to want and purchase the good or service.

Answer:
the principal amount at a rate of 4% is 2000
principal amount at a rate of 3.5% is 4000-2000 =2000
Explanation:
We have given total amount borrowed = $4000
Let x amount is borrowed at a rate of 4%
So $4000-x is borrowed at rate of 3.5%
Total interest = $150
We know that simple interest 
So 

0.5 x=1000
x = 2000
So the principal amount at a rate of 4% is 2000
And principal amount at a rate of 3.5% is 4000-2000 =2000
Answer:
the future value in two years is $110.25
Explanation:
The computation of the future value in two years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $100 × (1 + .05)^2
= $100 × (1.1025)
= $110.25
Hence, the future value in two years is $110.25
