The balance in Marty’s account will be $1330
Simple interest= (P x R x T) / 100
Where,
P = Principal = $1,000
R= Rate = 7.2%
T = Time = 55 months = 4.583333 years.
Simple Interest = (1000 x 7.2 x 4.58) / 100
=$329.76 = $330 (approx.)
Amount = Principal + Simple Interest
=$1000 + $330
=$1330
What is Simple Interest?
Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, so a borrower will never have to pay interest on the interest already accumulated because a creditor will only pay interest on the principal amount.
How do I calculate simple interest?
Simplified interest (S.I.) is computed using the following formula: S.I. = P*R *T, where P stands for principal, R for the annual percentage rate of interest, and T for time, which is typically expressed as the number of years. Written as r/100, the interest rate is expressed as a percentage, or r%.

Answer:
D. The quantity of car rentals demanded goes up.
Explanation:
Complimentary goods are products that are used together. If Airline travel and car rentals are complementary goods, it means the two products must be used together. Either of the products will not add much value to the customer if purchased alone.
Complimentary products have a joint demand. An increase in demand for one good leads to an increase in demand for the other product. If the demand for Airline travel rises, the demand for car rentals also increases. A decrease in demand will have similar effects.

It's c.
Explanation:
Program Evaluation and Review Technique (PERT) is a method used in program management. It analyzes the time required to complete each task in a project and so tries to determine the minimum time to complete a project. It was developed by the US Navy in 1957.
In PERT analysis:
- there are 3 time estimates for every activity: optimistic, pessimistic, and most likely
-
you have to find the Critical Path. The Critical Path is the longest path of scheduled activities that must be met in order to execute a project. It is important to know because any problems on the critical path can prevent a project from moving forward and be delayed. Therefore only critical activities can contribute to the project variance.
Answer: Producer price index
Explanation:
The producer price index is used to know the average differences in prices that are received by local producers for their output.
To calculate the producer price index, the current prices gotten by the sellers of a good or service is divided by the prices of the good or service using a base year and multiplying the result by 100. The producer price index is also a measure of inflation in an economy.
