Question 1115242: Hello! I'm a little stumped on this problem! Any help is greatly appreciated! Thank you so much for helping! So here's the problem:
For the regular plan, the minimum payment due is the greater of $10.00 or 5% of the new balance shown on your statement (rounded to the nearest $1.00) plus any unpaid late fees and returned check fees, and any amounts shown as past due on your statement.
If you make a purchase under a regular plan, no finance charges will be imposed in any billing period in which (i) there is no previous balance or (ii) payments received and credits issued by the payment due date, which is 25 days after the statement closing date shown on your last statement, equal or exceed the previous balance. If the new balance is not satisfied in full by the payment due date shown on your last statement, there will be a finance charge on each purchase from the date of purchase.
It's asking me this:
a) If the new balance in your account is $8 and you have $35 unpaid late fees, what is your minimum payment due?
b) Suppose you have a previous balance of $150 and you pay $200 one month after the statement closing date. Will you be assessed a finance charge?
c) In part b), if you make a purchase on the same day that you make the $200 payment, will a finance charge be assessed on that purchase?
Any help is greatly appreciated! Thank you so much!It really helps me!

Question 1115623: Appreciate your assistance on word problem below if you can solve it for me

B.Maria decides she can produce rose frames to supplement her income. She calculates that each medium frame requires a 6m length of timber and can be built in four minutes, while a large frame requires a 12m length of timber and can be built in six minutes.
She has a regular supply of suitable timber, a total length of 900 meters per week. She also has a maximum of 8 hours a week to build them.
Maria contacts the manager of a local chain of hardware stores. The manager is willing to stock Maria�s frame if she can guarantee at least 20 of each size per week, but will take no more than 60 of each size per week.
The deal will give Maria a $6 profit on each medium frame produced and a $10 profit on each large frame.
How many of each size frame should Maria produce to maximize her profit?

Question 1116232: This is Linear Programming Pls help us! :(
MILESTONE: Linear Program
After making various presentations to potential investors, MC has finally hit the jackpot. An investor wants to invest 100,000,000 pesos in MC.
After doing all your staff work in the previous weeks, the two of you have been tasked to find the most efficient way to invest the money. This involves making the highest profit possible from the money you have invested. You have decided to consult your friend Olivia, who is also a financial investor.
Olivia discusses that you need to use a mathematical method called Linear Programming to solve this problem. She explains that Linear Programming is a method that has to be set up very carefully. It involves creating a function to optimize and modelling various constraints using linear equations. She has decided to present you the profitability percentages of MC, given that she has already done prior work with MC.
The startup arm is projected to return at least 12%. To minimize risk, you must invest no more than 30,000,000 pesos. The financial stocks return 3%, while the retail arm returns 5%.
For tax reasons, you must invest at least 3 times more in the financial stocks than the retail arm.
Your task is to set up the linear program. You have to define the following:
1. The variables that will be used
2. The optimization function that will be used
a. What kind of optimization will be done: minimization or maximization?
3. The constraints that the linear program will be subjected to
